Real-time Spectral Band Optimization for Unmanned Aerial Systems (UAS) Hyperspectral Camera

To meet the need of the Navy in a hyperspectral imaging system with an automated analysis algorithm for optimum detection of specified target features, Applied Science Innovations, Inc. proposes development of the Coded-Aperture Hyperspectral Imager with Real-time Spectral Band Optimization (CAHIRSO). Communication channels of small tactical unmanned aerial systems (UAS) fall short of the bandwidth requirement of existing hyperspectral imaging systems. Communication hardware with adequate bandwidth exceeds the volume and weight allowance of such UAS. The patent-pending CAHIRSO hyperspectral camera with image formation and spectral selectivity will automatically control the type and amount of data to be transferred to the ground, in near real-time. The complete imaging system will be contained in a 4.75 inch diameter by 12 inch in length cylinder or smaller package. The spectrum coverage will be from 350 nm to 1.7 micron, with automatic gain control, manual gain control (addressable), selectable bandwidth, feature extraction, and low power. Phase I will establish feasibility of the CAHIRSO concept. In Phase II, a functional pre-production CAHIRSO prototype will be developed, demonstrated, and delivered to the Navy for evaluation and use, ready for UAS installation. In Phase III, CAHIRSO design will be further developed for integration on board UAS.
