摘要

In this article we present a novel optical sensor allowing simultaneous measurements of axial displacement and tangential velocity of moving rough solid state objects. The laser Doppler distance sensor with phase coding (P-LDDS) features multiple interference fringe systems which are superposed slightly tilted. The axial displacement of fast laterally moving rough solid state surfaces as well as of purely axial moving objects is determined via phase evaluation. Within a measurement range of 200 urn, the measured maximum systematic displacement error at a laterally moving rough solid state object is 1.4 urn and the displacement resolution is 240 nm. In contrast to conventional measurement techniques, such as triangulation, the displacement uncertainty is independent of the lateral object velocity. This unique feature can be utilized for precise displacement and vibration measurements of high speed objects.
