Abstract

We developed a prototype portable LWIR hyperspectral system based on a commercial microbolometer array and a spectral interferometer to test its utility in the field. The complete system with sensor head, tripod, scan motor and batteries weighs 10.5 lbs. Field tests show peak SNR near 250, and spectral analysis was able to detect specific minerals at geologic sites in Arizona. The project showed the feasibility of very low cost LWIR hyperspectral systems.
