Infrared Detectors

Analytical Chemistry, 1969
Infrared radiation has been studied with detectors of one kind or another since about 1800. The difference between the techniques of the first century-and-a-half and the period since World War II is that the earlier devices were thermal detectors, responding to temperature change caused by integrated absorption of energy, while the more recent devices ...

Infrared Detector

Physics Today, 1948
Since infrared or heat radiation of wavelength longer than about one micron cannot be detected by visual or photographic means, physicists, besides pushing development of standard radiation detectors such as thermopiles and bolometers, have roamed far afield in their attempts to find new and more sensitive infrared detectors.

Infrared Quantum Detectors

2020 43rd International Convention on Information, Communication and Electronic Technology (MIPRO), 2020
Quantum detectors respond to electromagnetic radiation by generating a photocurrent. The detection mechanism involves absorption of photons whose energy exceeds the band gap of the detector material. The absorption generates excited mobile charge carriers (electron-hole pairs) that form the photocurrent. The quantum detectors sensitive in near infrared

Thallium selenide infrared detector

Applied Optics, 1977
The application of semiconducting thallium selenide for ir detection is described. A responsivity of 10(6) V/W and NEP of the order of 10(-15) W/ radicalHz with a response time of 3 msec can be obtained by operating the detector at 1.5 K.
