Photodetector and array of photodetectors for the detection of light flashes and applications

摘要

The photosensitive detector (3) detects incoming laser light pulses (2). The pulses are converted to electrical energy. The energy is processed by a differential amplifier processor (4), which is colocated with the photsensitive detector. The differential amplifier reinforces signals with a rapid rise time produced by the laser pulses, and attenuates the slowly varying noise intensity signals produced by the photsensitive diode.
