At Eurosatory 2018, Ophir introduced another infrared thermal imaging lens to the range, the LightIR 15-75mm f/1.2, for uncooled 10–12-μm-pixel-size long–wave infrared (LWIR) detectors. [6] In 2019, Ophir expanded its family of cooled MWIR long range lenses, adding 900mm and 1350mm FLs, for use in aviation and observation systems. [7]
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 ...
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.
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 nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector.It is non-dispersive in the fact that no dispersive element (e.g a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.
