Quantum detectors for the ultraviolet, visible and near infrared

This article is devoted to quantum detectors covering the ultraviolet, visible and very near infrared spectral ranges. It describes the most common detectors, or photodiodes, based on the photovoltaic effect in junctions, as well as external photoelectric detectors for more specific applications, such as night vision.

These detectors, which are widely used in the civil, industrial, military and space sectors, come in a variety of forms:

• unit detectors ;

• detector arrays ;

• multibarrettes ;

• matrices ;

• low-light tubes.
