| 摘 要： | 针对现有激光自混合干涉(SMI)角度测量方法无法判别角度旋转方向的缺陷,提出一种基于SMI和表面等离子体共振(SPR)的、能判别旋转方向的角度测量方法.通过判断出射激光束的平均光强变化,确定被测物体旋转的方向;通过预先标定好的激光SMI输出光强和旋转角度间的对应关系,实现对被测物体旋转角度的测量.搭建了旋转平台微小旋转...

| Abstract: | Due to the fact that present angle measurement methods based on laser self-mixing interferometry(SMI) cannot determine the direction of angle rotation,we present an angle measurement method based on laser self-mixing interferometry and surface plasmon resonance(SPR) to solve this problem.The method determined the direction of angle rotation by the variation of related light intensity,and measured the rotation angle by the precalibrated correlation between the related light intensity and rotation... |
