How to select the appropriate photodetector?

According to the working principle and structure, photodetectors are generally divided into photoelectric detectors and thermoelectric detectors. Photoelectric detectors include vacuum photoelectric devices (photomultiplier tubes, etc.) and solid photoelectric detectors (photodiodes, photoconductive detectors, CCD, etc.).


Basic principle of acoustooptic modulator

Acousto-optic modulator is a device that can control the power, frequency or spatial direction of laser beam by using electronic driving signal. It uses the acoustooptic effect, that is, the refractive index is changed by the mechanical oscillation pressure of the sound wave.
