Phase error effect on contrast measurement in Schwider-Hariharan phase-shifting algorithm
Abstract:Abstract: Exact relationship due to linear phase error in contrast measurement in phase shifting interferometry using Schwider-Hariharan method has been obtained. Starting with five irradiance distributions, basic relationships for the contrast have been described.
