Infrared detector - Wikipedia
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.
Infrared detectors: an overview - ScienceDirect
Jun 1, 2002 · The paper presents progress in infrared (IR) detector technologies during 200 history of their development. Classification of two types of IR detectors (photon detectors and thermal detectors) is done on the basis of their principle of operation. The overview of IR systems and detectors is presented.
Detection of IR radiation is inherently more difficult than detection of visible light. The challenge has spawned many innovative techniques and the development of materials. IR detectors can be roughly divided into two classes: thermal and photonic. Thermal sensors experience a temperature change due to absorption of radiation.

Introduction in IR Detectors - SpringerLink
Feb 3, 2023 · Two types of detectors are currently used to detect infrared radiation – photonic (cooled and uncooled) and thermal. Thermal radiation detectors are non-selective devices, i.e. they have the same spectral characteristic over a wide range of the electromagnetic spectrum (up to hundreds of micrometers) [4, 23, 34].
