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 3 arcsec., Three-dimensional imaging, optical metrology, and inspection 5 : Conference : Sep 1999, Boston, MA}, pages = {14--21}, publisher = {International Society for Optical Engineering, SPIE}, title = {Small rotation angle measurement using an imaging method}, volume = {3835}, year = {1999} }
