Paper Abstract

The vectorial shearing interferometer is based on the Mach- Zehnder configuration, by incorporating the displacement shearing system, composed of a pair of wedge prisms that modify the optical path difference and the tilt of the sheared wave front with respect to that of the reference wave front. The variable shear and tilt may be implemented along any direction, by choosing the displacements Δx and Δy. The number of fringes and their orientation may be controlled with the shear direction and its magnitude. The shearing direction may be chosen along an arbitrary direction. A gradient of the phase function is obtained in any direction with the knowledge of the prescribed displacement in the x- and y-directions.
