Abstract

A system of rotation angle measurement based on the fringe projection is proposed and demonstrated. This system has potential for a broad range of uses and a robustness for the external disturbances, because it requires no coherent light. The setup is very simple and applicable to the automatic on- line measurement. Several measurements indicate a sensitivity of 5 arcsec.
