Abstract

A new method for measuring 3-D rigid body angle micro- displacements is proposed. Corresponding to the method a laser diode (LD) and a new CMOS image sensor (CIS) are used as a light source and a photodetector, respectively. The method can also be used to measure 1-D or 2-D displacements when required. Moreover, the paper also presents the experimental results, which demonstrate the new method has high accuracy, high processing speed, high reliability, and is easily realized.
