Polarimetric sensors are valued for their capability to distinguish man-made objects from surrounding clutter. The SPITFIRE (Spectral Polarimetric Imaging Test Field InstRumEnt) polarimetric camera is designed to function in multiple bands in the Short Wave Infrared (SWIR) and Mid-Wave Infrared (MWIR) regions. SPITFIRE is a Stokes micro-grid polarimetric system with a 4 band spectral filter wheel. The focal plane array (FPA) as well as the filter wheel are located in a Dewar which is cooled via liquid nitrogen. By cooling the band-pass filter to the same temperature as the FPA, self-emission noise is decreased. In this paper we discuss the design and fabrication of the polarimetric camera (optics, Dewar, filter wheel and FPA), the data capture and processing system, initial characterization of the camera's performance, and future plans for the camera.
