Abstract

An imaging polarimeter has been designed and constructed at the Air Force Phillips Laboratories to measure the polarization properties of laser speckle patterns. An imaging polarimeter spatially measures the polarization state of light coming from an object, thereby producing a `polarization image'. The system describes was designed to image the pupil of an optical system containing speckle patterns created by illumination of diffuse objects with light from a pulsed 1315 nm laser. Difficulties encountered due to demanding specifications required for polarimeter components and for coherent imaging systems in general are described and their solutions are discussed. Diagnostic techniques developed to measure path length differences and to identify the source of interference fringes are described. System calibration and characterization tests are described and results are presented.
