Abstract

A pair of thin prisms may be used to deviate the light beam without changing the image orientation in a vectorial shearing interferometer. The prism rotations determine the position of the wave front and the amount of its tilt. The separation between the prisms and their orientation determine the direction and the magnitude of the beam displacement. We designed a high precision mechanism with a fine resolution to rotate and displace each of two thin prisms. The device incorporates a two-axis calibration system. The angular resolution is 18 arc sec, with a periodic error of 3 arc sec, and a cumulative error of 10 arc sec is predicted.
