Paper Abstract

An interferometric spectrometer is proposed for low resource LWIR hyperspectral imaging. Scaling from an uncooled LWIR HSI system, we find that signal to noise ratios of 1000 or higher can be achieved with cooled detectors and uncooled optics. Signal flux is high enough to collect high quality data at very high rates (500Hz and above). Sensitivity is limited by the full well of the detector and the spectral resolution for scenes at typical temperatures.
