Optical Manufacturing and Testing III, 1999•spiedigitallibrary.orgScanning Deflectometry is a powerful method to measure optical figure quality of various
optical components and systems in a simple way. This principle uses detection of slope
deviations rather than optical path length variations. As an example, the design of a basic
deflectometer for testing flat mirrors is presented.
