Paper Abstract

The Polarization Phase Sensor (PPS) is a white light polarization shearing interferometer that has successfully demonstrated absolute mirror segment alignment in the Rome Laboratory Optical Systems Engineering Laboratory. Operating at the center of curvature, the PPS demonstration has been configured to perform closed-loop phasing of a three segment spherical mirror. The PPS may be adapted for use with other optical systems, including aspheric surfaces. PPS device simulation and testing have verified this. This paper will address the optical layout of the device, experimental testing, and the results of subsequent analysis.
