Description

TECHNICAL FIELD

[0001] The utility model relates to a light signal detection device, specifically a multi-angle light signal detection device. BACKGROUND

[0002] The light signal detection device, i.e. the light detector, is a device capable of detecting and measuring light signals. Such devices have a wide range of applications in various fields, including but not limited to optical communication, spectral analysis, scientific research, industrial automation, environmental monitoring, and security and defense. The light detector, also known as the light detector, is the primary part of the optical receiver and an important component of the optical fiber sensor. It can detect the optical power incident on its surface and convert the change in optical power into corresponding current. According to the working principle and structure, the light detector is usually divided into two categories: photodetectors and thermoelectric detectors. Among them, photodetectors include vacuum photodetectors (such as photomultiplier tubes) and solid-state photodetectors (such as photodiodes, photoconductive detectors, CCDs, etc.). The basic working principle of photodetectors is to convert optical signals into electrical signals. When light shines on a semiconductor material, photons will hit electrons in the semiconductor material, causing them to transition to the conduction band, thereby forming hole and electron pairs. This effective carrier pair (electron-hole pair) will move in the semiconductor and form a current when an external bias is applied. Taking a photodiode as an example, under a reverse voltage, there is no light, and the reverse current is extremely weak (called dark current); when there is light, the reverse current increases rapidly (called photocurrent), and the greater the intensity of the light, the greater the reverse current. This change in photocurrent can be used to represent the change in optical signal, thereby achieving the conversion of optical signals to electrical signals. Within the wavelength range required by the system, it has high quantum efficiency, can detect weak optical signals, can cover different wavelengths of optical signals from ultraviolet to infrared, meets the needs of high-speed data transmission, and can quickly respond to changes in optical signals. The application fields of light detectors include optical communication, industrial automation, environmental monitoring, and other military applications such as infrared guidance, laser radar, missile tracking, and fire control systems, which play an important role in achieving military target tracking, reconnaissance, and defense.
