Abstract
Field tests in a variety of scenarios indicate significant advantages to using polarization for enhancing target detection in cluttered backgrounds or backgrounds with countermeasures. Polarization provides additional information in these difficult detection scenarios and has strong potential to address a variety of Army and MDA needs. For midcourse scenarios, debris and decoy clouds, low thermal contrast, and target orientation determination can be addressed through the proposed imaging polarimeter. For the re-entry phase of an RV's trajectory, this imaging polarization sensor can provide aimpoint selection and orientation determination in the presence of a wake in the same manner as for boost phase in the presence of a plume. Polaris Sensor Technologies is developing such an imaging polarimeter incorporating an on-demand polarizer based on liquid crystal (LC) technology. The liquid crystal cell modulates the polarization rather than the intensity of the transmitted light. When the polarization mode is switched off, the liquid crystal does not limit the amount of unpolarized light reaching the focal plane due to the inherent loss of photons at the polarizer. This effort results in an imaging polarimeter operating in the visible spectrum.
