INFRARED DETECTOR

摘要

Infrared radiations are radiations below (infra) visible spectrum. This emergent dual use technology field is fast emerging amongst the most ubiquitous ones. It spans from low-end automatic supermarket door openers to high-end space based detectors used to detect nuclear tests, missiles and intra galactic radiations. At the heart of this technology is the IR detector. Objective of this report is to review infrared (IR) detectors. Evolution of IR technology has been largely synonymous to advances in IR detectors. Various types of detectors, formats and materials interlaced with their applications have been studied.
