Paper Abstract

A Wollston prism with polarizing elements is used in optical interferometry. Double light source images can be to shear by the prism and to control exposes. According to shear theory, the optical effect caused by the deflection in this arrangement is formed frequency grating and/or carrier fringe pattern. The projects of classical, holographic, speckle interferometry, etc. can be to investigate with this modulator.
