19 September 2016 Data processing for a multi-slit LWIR HSI spectrometer

Preliminary testing of a three-slit prism-based spectrometer is presented to test means of exploiting data from a multi-slit spectrometer as well as some potential ways of dealing with complications that arise when using multiple slits. When using a multiple slit spectrometer to boost SNR there are two primary concerns: first, the spectral axis of each slit must be nearly identical to effective average and second, the image from each slit must be well-registered. Based on some of these complications it seems, given the current technology, the best operational mode is to use the sensor to increase area coverage.
