An infrared detector is a detector that reacts to infrared (IR) radiation. The two main types of detectors are thermal and photonic (photodetectors). The thermal effects of the incident IR radiation can be followed through many temperature dependent phenomena. [2] Bolometers and microbolometers are based on changes in resistance.
A FLIR Talon multi-sensor camera system equipped with an infrared laser pointer (which is invisible to casual observers) for illumination purposes was used to gather data at night. [15] The American Civil Liberties Union raised concerns over the fact that new surveillance technology is implemented without judicial guidance and public discussion ...
Thermal Infrared Image by Mars Odyssey's thermal emission imaging system of Mars. Thermal remote sensing is a branch of remote sensing in the thermal infrared region of the electromagnetic spectrum. [1] Thermal radiation from ground objects is measured using a thermal band in satellite sensors. [2]
IRST systems re-appeared on more modern designs starting in the 1980s with the introduction of 2-D sensors, which cued [clarification needed] both horizontal and vertical angle. Sensitivities were also greatly improved, leading to better resolution and range. In more recent years, new systems have entered the market.
In January 2004, FLIR acquired Indigo Systems, a developer and supplier of infrared imaging products, including cooled and uncooled infrared detectors, camera cores, and finished cameras, for $190 million. [24] In 2011, after losing a trade secrets claim against the founders of Indigo Systems, FLIR agreed to pay $39 million to settle a countersuit.
A thermal sensor is a device able to detect the thermal radiation emitted by an object located in the FOV(Field Of View) of the sensor. Infrared radiation ( IR ) striking the sensor produces a change in the temperature of the device that as a consequence generates an electric output signal proportional to the incident IR power.
A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors . PIR sensors are commonly used in security alarms and automatic lighting applications.
Common Infrared Countermeasures (CIRCM) is a laser-based IR countermeasure against current and future IR threat systems for the US Army rotorcraft and fixed wing platforms and US Navy and US Air Force rotorcraft platforms. Systems by BAE Systems, ITT Defense and Information Solutions, Northrop Grumman and Raytheon were under consideration. In ...
