Abstract :
An overview of the latest efforts in integrated polarization imaging sensors are presented. We describe two approaches for creating focal plane polarization imaging sensors. The first approach combines polymer polarization filters with CMOS active pixel sensor and computes polarization information at the focal plane. The second approach outlines our initial work on polarization filters using aluminum nano wires. Measurements from the first polarization image sensor prototype are discussed in detail and applications for material detection using polarization techniques are described.
