Remote sensing
 
26:32
Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to in situ observation. In modern usage, the term generally refers to the use of aerial sensor technologies to detect and classify objects on Earth (both on the surface, and in the atmosphere and oceans) by means of propagated signals (e.g. electromagnetic radiation). It may be split into active remote sensing, when a signal is first emitted from aircraft or satellites) or passive (e.g. sunlight) when information is merely recorded.

"Remote sensing" is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to on site observation. Remote sensing is a sub-field of geography. In modern usage, the term generally refers to the use of aerial sensor technologies to detect and classify objects on Earth by means of propagated signals . It may be split into active remote sensing or passive when information is merely recorded. Passive sensors gather radiation that is emitted or reflected by the object or surrounding areas. Reflected sunlight is the most common source of radiation measured by passive sensors. Examples of passive remote sensors include film photography, infrared, charge-coupled devices, and radiometers. Active collection, on the other hand, emits energy in order to scan objects and areas whereupon a sensor then detects and measures the radiation that is reflected or backscattered from the target. RADAR and LiDAR are examples of active remote sensing where the time delay between emission and return is measured, establishing the location, speed and direction of an object. Remote sensing makes it possible to collect data of dangerous or inaccessible areas. Remote sensing applications include monitoring deforestation in areas such as the Amazon Basin, glacial features in Arctic and Antarctic regions, and depth sounding of coastal and ocean depths. Military collection during the Cold War made use of stand-off collection of data about dangerous border areas. Remote sensing also replaces costly and slow data collection on the ground, ensuring in the process that areas or objects are not disturbed.

Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to on-site observation. Remote sensing is used in numerous fields, including geography and most Earth Science disciplines (for example, hydrology, ecology , oceanography, glaciology, geology); it also has military, intelligence, commercial, economic, planning, and humanitarian applications. In current usage, the term "remote sensing" generally refers to the use of satellite- or aircraft-based sensor technologies to detect and classify objects on Earth, including on the surface and in the atmosphere and oceans, based on propagated signals (e.g. electromagnetic radiation). It may be split into "active" remote sensing (i.e., when a signal is emitted by a satellite or aircraft and its reflection by the object is detected by the sensor) and "passive" remote sensing (i.e., when the reflection of sunlight is detected by the sensor).

Military collection during the Cold War made use of stand-off collection of data about dangerous border areas. Remote sensing also replaces costly and slow data collection on the ground, ensuring in the process that areas or objects are not disturbed. Orbital platforms collect and transmit data from different parts of the electromagnetic spectrum, which in conjunction with larger scale aerial or ground-based sensing and analysis, provides researchers with enough information to monitor trends such as El Nino and other natural long and short term phenomena. Other uses include different areas of the earth sciences such as natural resource management, agricultural fields such as land usage and conservation, and national security and overhead, ground-based and stand-off collection on border areas.

What is DATA ACQUISITION? What does DATA ACQUISITION mean? DATA ACQUISITION meaning - DATA ACQUISITION definition - DATA ACQUISITION explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Data acquisition is the process of sampling signals that measure real world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. Data acquisition systems, abbreviated by the acronyms DAS or DAQ, typically convert analog waveforms into digital values for processing. The components of data acquisition systems include: 1. Sensors, to convert physical parameters to electrical signals. 2. Signal conditioning circuitry, to convert sensor signals into a form that can be converted to digital values. 3. Analog-to-digital converters, to convert conditioned sensor signals to digital values. Data acquisition applications are usually controlled by software programs developed using various general purpose programming languages such as Assembly, BASIC, C, C++, C#, Fortran, Java, LabVIEW, Lisp, Pascal, etc. Stand-alone data acquisition systems are often called data loggers. There are also open-source software packages providing all the necessary tools to acquire data from different hardware equipment. These tools come from the scientific community where complex experiment requires fast, flexible and adaptable software. Those packages are usually custom fit but more general DAQ package like the Maximum Integrated Data Acquisition System can be easily tailored and is used in several physics experiments worldwide. In 1963, IBM produced computers which specialized in data acquisition. These include the IBM 7700 Data Acquisition System, and its successor, the IBM 1800 Data Acquisition and Control System. These expensive specialized systems were surpassed in 1974 by general purpose S-100 computers and data acquisitions cards produced by Tecmar/Scientific Solutions Inc. In 1981 IBM introduced the IBM Personal Computer and Scientific Solutions introduced the first PC data acquisition products. Data acquisition begins with the physical phenomenon or physical property to be measured. Examples of this include temperature, light intensity, gas pressure, fluid flow, and force. Regardless of the type of physical property to be measured, the physical state that is to be measured must first be transformed into a unified form that can be sampled by a data acquisition system. The task of performing such transformations falls on devices called sensors. A data acquisition system is a collection of software and hardware that lets you measure or control physical characteristics of something in the real world. A complete data acquisition system consists of DAQ hardware, sensors and actuators, signal conditioning hardware, and a computer running DAQ software. A sensor, which is a type of transducer, is a device that converts a physical property into a corresponding electrical signal (e.g., strain gauge, thermistor). An acquisition system to measure different properties depends on the sensors that are suited to detect those properties. Signal conditioning may be necessary if the signal from the transducer is not suitable for the DAQ hardware being used. The signal may need to be filtered or amplified in most cases. Various other examples of signal conditioning might be bridge completion, providing current or voltage excitation to the sensor, isolation, linearization. For transmission purposes, single ended analog signals, which are more susceptible to noise can be converted to differential signals. Once digitized, the signal can be encoded to reduce and correct transmission errors.

Multivariate probability model for 3-layer remote sensing
 
20:36
We develop a multivariate probability model for a 3-layer radiative transfer equation, which can be used to predict the stochastic nature of measured signals for multispectral and hyperspectral remote sensing applications. A multivariate 3-layer model is particularly important because the remote sensing problem is typically clutter limited, meaning that variability from the scene - temporal or spatial changes in environmental parameters collectively called “clutter” - is greater than sensor noise and thus is the limiting factor in determining whether a particular target of interest can be detected. Our model is derived from physical considerations regarding expected statistics for blackbody radiation, transmission, and radiance, and is described by the Johnson system of distributions. With the model we obtain pdfs of the target radiance, background radiances, and thermal contrast, and obtain new physical insights on the remote sensing scenario.

Types of Sensors│ Different types of sensors│ Classification of sensor│
 
04:01
Types of Sensors│ Different types of sensors│ Classification of sensor│ Hi everybody, today I will share about Types of Sensor. This video you learn following about Types of Sensor. Sensors are classified based on the nature of quantity they measure. Following are the types of sensors with few examples. 1. Acoustic and sound sensors. A sensor is used to measure sense an environment and converts this information into a digital or analogue data signal that can be interpreted by a computer or observer. An acoustic wave sensor is an electronic device that can measure sound levels. For Example, Microphone, Hydrophone. 2. Automotive sensors. Automotive sensor is one of the largest sensor companies in the world, with innovative sensor solutions that help customers transform concepts into smart, connected creations. For example, Speedometer, Radar gun, Speedometer, fuel ratio meter. 3. Chemical Sensors. A chemical sensor is a device that transforms chemical information composition, presence of a particular element or ion, concentration, chemical activity, partial pressure into an analytically useful signal. For example, Ph sensor, Sensors to detect presences of different gases or liquids. 4. Electric and Magnetic Sensors. Magnetic sensors differ from most other detectors in that they do not directly measure the physical property of interest For example, Galvanometer, Hall sensor measures flux density, Metal detector. 5. Environmental Sensors. Environmental sensors include barometric pressure sensors as well as integrated environmental sensors. These integrated sensors combine barometric air pressure, humidity, ambient air temperature sensing functions as well as air quality measuring. For example, Rain gauge, snow gauge, moisture sensor. 6. Optical Sensors. Optical sensors are electronic detectors that convert light, or a change in light, into an electronic signal. They are used in many industrial and consumer applications, For example, Photo diode, Photo transistor, Wave front sensor. 7. Mechanical Sensors. Mechanical sensors are used for positioning and limit switch tasks on machine tools and presses, flexible production centers, robots, assembly and conveying equipment, and in machine and plant construction. For decades, they have proven their worth as the traditional strongmen of automation. For example, Strain Gauge, Potential meter measures displacement. 8. Thermal and Temperature sensors. The thermal response of a temperature sensor is the speed at which it responds to a sudden change in temperature. Thermal response time is the time taken for the sensor to react to this change in temperature. For example, Calorimeter, Thermocouple, Thermostat, Gordon gauge. 9. Proximity and Presences sensors A proximity or presences sensor is the one which is able to detect the presences of nearby objects without any physical contact. They usually emit electromagnetic radiations and detect the changes in reflected signal if any. For example, Doppler radar, Motion detector. Thanks for watching my tutorial videos.

How to make infrared proximity sensors | without IC using only transistor.
 
01:33
The basic concept of an Infrared Sensor which is used as Obstacle detector is to transmit an infrared signal, this infrared signal bounces from the surface of an object and the signal is received at the infrared receiver. There are five basic elements used in a typical infrared detection system: an infrared source, a transmission medium, optical component, infrared detectors or receivers and signal processing. Infrared lasers and Infrared LED’s of specific wavelength can be used as infrared sources. The three main types of media used for infrared transmission are vacuum, atmosphere and optical fibers. Optical components are used to focus the infrared radiation or to limit the spectral response. Optical lenses made of Quartz, Germanium and Silicon are used to focus the infrared radiation. Infrared receivers can be photodiodes, phototransistors etc. some important specifications of infrared receivers are photosensitivity, detectivity and noise equivalent power. Signal processing is done by amplifiers as the output of infrared detector is very small.

GIS and REMOTE SENSING by Darshan Singh in HINDI
 
12:25
Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to on-site observation, especially the Earth. Remote sensing is used in numerous fields, including geography, land surveying and most Earth Science disciplines (for example, hydrology, ecology, meteorology, oceanography, glaciology, geology); it also has military, intelligence, commercial, economic, planning, and humanitarian applications. In current usage, the term "remote sensing" generally refers to the use of satellite- or aircraft-based sensor technologies to detect and classify objects on Earth, including on the surface and in the atmosphere and oceans, based on propagated signals (e.g. electromagnetic radiation). It may be split into "active" remote sensing (i.e., when a signal is emitted by a satellite or aircraft and its reflection by the object is detected by the sensor) and "passive" remote sensing (i.e., when the reflection of sunlight is detected by the sensor)

China plans space-based, solar-powered telecom drones China’s solar-powered telecom drones can fly as high as 20 km above the ground for days and can undertake remote sensing and relay signals In Beijing: China is planning to build a space-based, solar-powered drone telecommunications network capable of providing week-long emergency assistance on the ground, according to a state media report on Wednesday. A research institute affiliated with China Aerospace Science and Industry Corp is developing the project “Feiyun,” which means “flying cloud,” the Global Times reported, citing another report in the Science and Technology Daily. The network will be based in “near space”, it said, adding the system will be able to provide week-long emergency communications access and likely to go on trial this year. The drones can fly as high as 20 km above the ground for days—somewhat like a telecommunications satellite—and can undertake remote sensing and relay signals, the report quoted Ma Hongzhong, head of the institute, as saying.

IO-Link digital signals
 
01:50
Analog signals are traditionally used for process control but have serveral drawbacks. Sensing element provides an analog signal. Analog signal is converted to digital to be processed by the sonsor The signal must be converted back to analog to be transmitted to the control system over shielded cable to prevent external influences. IO-Link communication transmits the data digitally for reliable process control. Sensing element signal is converted only once and transmitted digitally over standard cable to the IO-Link Master and then to the process controller. More about IO-link: http://www.ifm.com/gb/io-link

Pablo Rodriguez: "Trace Gases in Remote Oceanic Regions" | Talks at Google
 
50:10
Pablo is a visiting ETH researcher at the time of this talk. Pablo’s PhD focuses on DMS, Isoprene and Methyl Iodide. The marine emission of these trace gases contributes to marine aerosol formation and,consequently, they are able to trigger important climatic roles.Therefore, in order to understand the mechanisms involved in these processes, Pablo combines bio optical and in situ data, from oceanographic cruises to fieldwork on islands, with ecological modelling and remote sensing tools. Ultimately, the goal is to develop novel mathematical models implementing the biogeochemical processes related to the target trace gases, with the aim of assessing its climatic relevance under the current context of global change. Pablo has been involved in several oceanographic research projects, spending in total more than 4 months on research cruises. He has fieldwork expertise at: Mediterranean Sea, North Sea, Indian Ocean, Atlantic Ocean and Antarctic Ocean.
