【摘要】 PSD是一种利用半导体的“横向光电效应”制成的光电位敏探测器。这里介绍了PSD(position- sensitive detector)同步检测多路光位置信号的新方法。实验系统通过PAM(脉冲幅度调制)调制的方法来实现对多路光位置信号的同步检测。从理论上论证了这种新检测方法的实用性和可行性,并从硬件电路上进行了设计研制。更多还原

【Abstract】 PSD is a photoelectronic position-sensitive detector based on lateral photoeffect. It shows a new method that synchronous detecting multiple light beams’ position with PSD. This technology relies on PAM(pulse amplitude modulate) to detect multiple light beams synchronously. Its practicability and feasibility in theory are proved, and the experiments on the circuit design to realize this technology are done.更多还原
