Abstract
Polarization imaging holds promise for providing significant improvements in contrast in a number of target detection and discrimination applications. In several recent development efforts, it has been demonstrated that manmade objects have a significantly stronger polarization signal than natural backgrounds resulting in good contrast that complements the conventionally imaged infrared signature. Other recent research has suggested that polarization sensing may increase detection range through optically dense media such as fog or aerosol laden atmosphere. However, these experimental systems frequently require long data acquisition times, which results in artifacts in the polarization imagery due to platform or target motion. Additionally, calibration and investigation of systematic errors in these systems is difficult and robust calibration procedures have not been fully demonstrated. Polaris Sensor Technologies, Inc is proposing to develop an MWIR imaging polarimeter that captures a complete Stokes vector image in a single image. The approach chosen utilizes birefringent wedge polarization components in a unique configuration that eliminates polarization artifacts due to target or platform motion. In Phase I, the prototype instrument was designed complete with component specifications and schematics. In Phase II, the system will be built. Models of the novel birefringent wedge system and the complete optical system will be developed.
