Overview

ABSTRACT

This article is dedicated to quantum detectors encompassing the following spectral domains: ultraviolet, visible, very close infrared. It describes the most widely used detectors, or photodiodes, based on the photovoltaic effect in junctions, as well as the external photoelectric effect detectors, destined to more specific applications such as night vision. Widely used in the civil, industrial, military and space sectors, these detectors appear in various forms: unit detectors, array detectors, multiarray, photomultiplier tubes for low light.

Read this article from a comprehensive knowledge base, updated and supplemented with articles reviewed by scientific committees.

INTRODUCTION

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:
