摘要
本文提出了测量球面无标记物体定轴转动角位移的客观散斑法。通过记录球面散射的散斑位移,计算球面物体的定轴角位移,并给出了实验验证。测量方法简单、测量精度高。实验结果与理论相符。
A method for measuring angular displacement of markless objects with sphericalsurface is presented in this paper. Some theoretical conclusions are obtained and approved byexperiments. The method is approved to have features of simplicity,practicality and high ac-curacy. The conclusions are experimentally extended to general cases.
