A system of small-rotation-angle measurement based on fringe projection is proposed and demonstrated. This system has potential for a broad range of uses and robustness to external disturbances, because it requires no coherent light. The setup is very simple and applicable to automatic on-line measurement. Several measurements indicate a sensitivity of 3 arcsec.
