Abstract

In this paper we present a new class of high-performance infrared imagers utilizing near-critical angle spatial filters. The integrated photonic device design and nanofabricated thin-film optical coating are relatively simple but promise significant performance and image quality improvements, as well as reduction of cost, Size, Weight, and Power (cSWaP). Many of the common questions related to this technological approach are addressed and answered, including thermal isolation, spectral dependence, ambient temperature sensitivity, and sub-diffraction limit pixel size. Calculations are provided to access the expected performance, which indicate significant advantages to this technological approach.
