Abstract

Development of two prototype field-portable hyperspectral imagers that will also collect polarization signatures is being carried out in the visible-near infrared (VNIR) and the shortwave infrared (SWIR) regions. Each of these imagers uses a TeO₂ noncollinear acousto-optic tunable filter (AOTF) and two liquid crystal variable retarders (LCVRs). The spectral region of operation for the first imager is from 400 to 800 nm and for the second one from 900 to 1700 nm. We will present the optical design and Mueller Matrix analysis results.
