Problems solved by technology

[0002] In the prior art, common four-quadrant photodetectors generally use ordinary PIN photodiode detectors. Compared with avalanche detectors, PIN photodiode detectors have a lower signal-to-noise ratio and a shorter detection distance. Four-quadrant photodetection systems with diode detectors have lower performance

Description

technical field [0001] The invention relates to a photoelectric detector assembly, in particular to a four-quadrant avalanche detector assembly. Background technique [0002] In the prior art, common four-quadrant photodetectors generally use ordinary PIN photodiode detectors. Compared with avalanche detectors, PIN photodiode detectors have a lower signal-to-noise ratio and a shorter detection distance. Four-quadrant photodetection systems with diode detectors have lower performance. Contents of the invention [0003] Aiming at the problems in the background technology, the present invention proposes a four-quadrant avalanche detector assembly. Composed of detector, refrigerator and four-way amplifier circuit; [0004] The lower end of the tube shell is welded and fixed to the upper end surface of the tube seat, and the upper end of the tube shell is provided with a light window; the area covered by the tube shell on the tube seat forms an installation area; Set in the ...
