Abstract
The method of shearing interferometry is used for the slope and curvature measurement of thin plates. Several methods are proposed for a plate model with a specularly reflecting surface. Slope contours are also obtained for a diffusely reflecting model.
Several adaptable shearing interferometers are discussed. Experiments are performed to verify the feasibility of the methods with emphasis on the use of a Wollaston prism as the shearing mechanism.
