 note = {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., Optical engineering for sensing and nanotechnology : International conference on optical sensing and nanotechnology : Jun 1999, Yokohama, Japan},
