Broadband Polarization and Color Sensitive Focal Plane Array with Thick Optical Filter and Micro-optics Array
Researchers at the University of Arizona have designed a sensor array with thick IR filters and micro-optics for use in a polarization and color camera. The camera is wide-angle and broad band, yet its design greatly reduces cross-talk between pixels and maintains high resolution.
Background:
Polarization imaging is key in fields like medicine, remote...

Patternable Circular Color Polarizer and Filter Based on Cholesteric Liquid Crystal Polymer
This technology consists of a process to fabricate micro-polarizer and wave plate based on nematic liquid crystals. University of Arizona inventors have improved upon that technology and have identified a process to create a circular polarizer for various visible wavelengths using a cholesteric liquid crystal (ch-LCP).
Background:
Linear micropolarizer...
