Abstract
A pixel-level micropolarizer array bonded to a scientific camera has been developed for use in commercial dynamic interferometers. The pixelated array includes the 0, 45, 90, and, 135 degree polarization orientations. Micropolarizer arrays with elements as small as 7.4 microns and array sizes as large 4 Mega-pixels have been fabricated for use across the visible spectrum. The pixelated polarization camera acquires the four polarization orientations in a single video frame, which enables instantaneous interferometric or polarimetric measurements. Examples of each type of measurement are presented. Details of how the pixelated camera is used in interferometry are reviewed and the spatial resolution performance of the camera when used in interferometry is discussed.
