Infrared detectors: an overview - ScienceDirect

01/06/2002· His latest bolometer could detect the heat from a cow at a distance of a quarter of mile. Thus, at the beginning the development of IR detectors was connected with thermal detectors. The photon detectors were developed in XX century. The first IR photoconductor was developed by Case in 1917 . In 1933 Kutzscher at University of Berlin, discovered that lead sulphide (from natural galena …

History of infrared detectors - Antoni Rogalski

Infrared detectors are in general used to detect, image, and measure patterns of the thermal heat radia− tion which all objects emit. At the beginning, their development was connected with thermal detectors, such as ther− mocouples and bolometers, which are still used today and which are generally sensitive to all infrared wavelengths and op− erate at room temperature. The second kind of ...

Thermoception - Wikipedia

Thermoception or thermoreception is the sensation and perception of temperature, or more accurately, temperature differences inferred from heat details of how temperature receptors work are still being investigated. Ciliopathy is associated with decreased ability to sense heat, thus cilia may aid in the process. Transient receptor potential channels (TRP channels) are believed to play ...

Chapter 1 Infrared Detector Characterization

Infrared Detector Characterization 5. photon detectors show a selective wavelength dependence of response per unit incident radiation power. Their response is proportional to the rate of arrival photons as the energy per photon is inversely proportional to wave-length. In consequence, the spectral response increases linearly with increasing wavelength [see Fig. (a)], until the cutoff ...

Infrared technology and thermal cameras: How they work

Infrared detectors make it possible to “see” in the dark by converting heat emitted naturally by any object above absolute zero into an electronic signal, which is then used to generate an image. The discovery. Infrared radiation was discovered in 1800 by the British astronomer Sir William Herschel. He directed sunlight through a prism and placed a thermometer just outside the red end of ...
