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...

A Broadband Apparatus for Generating and Sampling Polarization States
Researchers at the University of Arizona have developed thin-film polarization devices that generate and/or sample light-polarization states over a broad band (wide wavelength range) and over wide angles. The polarizers incorporate and exploit multiple polarization layer groups and can be integrated into a microarray and incorporated into a light source...
