摘要
在“微型机械旋转运动动态参数测试仪”研制过程中采用微动光阑提取微电机动态信号，此微动光阑连续可调，直至闭合，其微调量比普通光阑小几倍至一个数量级，可提取光束直径在０～２ｍｍ以内的光信号，再配以光敏接收器的选择和部份机械结构的设计，成功地实现了微弱动态信号的提取，这对尚处于摸索阶段的微图形动态测量具有重要意义。
In accordance with the measuring characteristic,a scheme of untouched measurementbased on the optoelectronic measurement principle in reflect style is presented.The focalpoint of the work is drawing faint revolving signal,thus designed a precision optical fence,which may be continuously adjusted untill to be closed.its fine tuning quantity is much lessthan ordinary optical fence(so far as to reach a order of magnitute),using this optical fencemay pick up the signal that light spot diameter in range of 0 to 2mm. Adopting this precisionoptical fence,cooperating with choosing corectly photoelectric receiver and designing a part ofmachanical structure,realized the drawing to faint revolving signal.This is importance formicropicture dynamic measuremant in the stage of exploring.
