Abstract

In 2014, we laid out the theory for how a 2×4 microgrid polarimetric array provides superior spatial resolution when compared to a conventional 2×2 array. In this paper, we provide experimental evidence to support our claims via a prototype 2×4-patterned infrared microbolometer camera developed by Polaris Sensors Technologies. The benefits of the 2×4 array are obtained through a combination of the physical arrangement of the pattern itself and though the application of a log-based framework for reconstructing degree and angle of linear polarization directly, without calculating Stokes parameters or interpolating intensity channels as intermediate steps.
