Abstract
We report on the design, fabrication and performance of the Rochester Institute of Technology Polarization Imaging Camera (RITPIC). Despite great advances in astronomical (and terrestrial remote sensing) instrumentation, the measurement of polarization of light remains challenging and infrequent. Recently, the fabrication of micropolarizer arrays has allowed the development of compact polarimeters which promise to make polarimetry more accessible. These devices are capable of measuring the degree of polarization (DoP) and angle of polarization (AoP) across a scene using a single exposure (“snapshot”). They are compact, light-weight and mechanically robust, making them ideal for deployment on space-based platforms. We present the performance of such a polarimeter and describe the kind of science that is possible with RITPIC and future generations of these revolutionary devices.
