[0002] The principle of photoelectric detectors is that radiation causes the conductivity of the irradiated material to change. Photoelectric detectors are widely used in various fields of military and national economy. In the visible light or near-infrared bands, they are mainly used for ray measurement and detection, industrial automatic control and photometry, etc. In the infrared band, they are mainly used for missile guidance, infrared thermal imaging and infrared remote sensing.

[0003] The existing 10GHz amplified photodetector is not convenient to be sealed and protected when not in use, so dust easily adheres to the surface of the detection port exposed to the outside world. The photodetector is also easily touched by external forces. In addition, it is not convenient to provide heat dissipation protection for the photodetector when in use. The heat accumulation of the photodetector after long-term operation can easily reduce its service life, making it less practical.
