High sensitivity tilt measurement by speckle shear interferometry
Abstract
Speckle shear interferometry is used for measuring the tilt of diffuse objects with high sensitivity. The theory of tilt measurement using rotational, inversion, and folding shears is given, and experimental results are presented. Experimental configurations to achieve both inversion and folding shears simultaneously are given.
