1. An amplitude modulated laser rangefinder : electronic circuit design and implementation
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Signaler och systemSammanfattning : This report describes the design and implementation of a prototype for an amplitude modulated laser rangefinder, which is made on a PCB consisting of a laser module emitting light, a photodiode receiving the light reflected from the target, and other components. The design is made for the different power levels, generation of the modulation output and the reception of the signal. LÄS MER
