IR detector

(InfraRed detector) A sensing device that picks up radiation in the infrared band. Used extensively for still and video night vision cameras, cooled IR detectors can sense the makeup of nebulae light years in the distance. IR detectors are expected for many applications beyond night vision, including irregularities in machinery, ice on aircraft wings and faults in circuit boards.

Infrared detection works because most everything in our known world gives off heat, which emits radiation in the infrared band. The first IR detector actually dates back to 1800 when prisms were used to detect this band. By 1900, objects could be detected as far as a quarter mile in the distance. See infrared, IR remote control and IrDA.


IR Sensing in a Digital Camera
In 2001, Sony introduced the F707, its first digital camera with infrared sensing. The viewfinder at top uses the light in the room, while the bottom image shows the view with "Night Framing" turned on.

The noise found in the MVS thermistor signal is related to the noise found in the MVS IR signal, as they are both obtained using the same sensing element with the IR detector using the thermistor to provide a reference temperature.

The [GPC.sub.IR] can be configured as a triple detector system, including a viscometer and light scattering and IR detector, with both concentration and composition sensors for SCB measurement The IR detector is the new IR4 + or Optionally the IR5-MCT.
The altered (attenuated) energy from each evanescent wave is passed back to the IR beam, which then exits the opposite end of the crystal and is directed at an IR detector. The detector records the attenuated IR beam as an interferogram signal, which is used to generate an IR spectrum.
