Abstract

Deployable polarimetric imaging systems often use 2×2 arrays of linear polarizers at the pixel level to measure the polarimetric signature. This architecture is referred to as a micro-grid polarizer array (MPA). MPAs are either bonded to or fabricated directly upon focal plane arrays. A key challenge to obtaining polarimetric measurements of sub-pixel targets using MPAs is registering the signals from each of the independent channels. Digital Fusion Solutions, Inc has developed a micro-optic approach to register the fields of view of 2x2 subarrays of pixels and incorporated the device into the design of a polarimetric imager. Results of the design will be presented.
