Photodetecting device, laser pulse detector comprising such device and a laser pulse detecting device comprising such laser pulse detectors

摘要

A photosensor (3) transforms received luminous energy into electric current. A processor (4) has a cascoded inverting amplifier (5) and slow follower-type feedback (6). The feedback has identical N-type metal oxide semiconductor (NMOS) transistors (10,11) which are arranged in series, and supplied with electric current output by the photosensor. The processor processes the generated electric current. Independent claims are also included for the following: (1) laser pulse detector; and (2) laser pulse detection device.
