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. When the shearing direction is chosen along the CCD pixels rows and columns, a two-dimensional derivative of the phase function is obtained, allowing its complete recovery in two- dimensions. The variable shear and tilt may be implemented along any direction, by choosing the displacements (Delta) x and (Delta) y. The number of fringes and their orientation may be controlled with the shear direction and its magnitude.
