OP500C InGaAs 4×4 single photon array detector component (hereinafter referred to as “detector”) consists of InGaAs avalanche photodiode 4×4 array chip, active and passive fast quenching circuits, refrigeration circuits, signal control circuits and other components.
The size of the detector array is 4×4 elements, the distance between the centers of the elements is 100 μm, and the operating wavelength is 1.0-1.65 μm near infrared wavelength.The detector has high detection sensitivity and is capable of detecting weak optical signals (single-photon signals); each image of the detector operates freely within an adjustable pulse width, and each image independently outputs detection signals and processes the output electrical signals, with minimal influence by noise. The detector assembly is characterized by high sensitivity, simple system structure, etc. It can be applied to long-distance laser distance measurement, long-distance laser distance measurement, long-distance laser distance measurement, long-distance laser distance measurement, and so on.
