Fanbeam hyperspectral acquisition for underwater applications

The Fanbeam Spectral Imager (FSI) system provides high area coverage rate acquisition of 3D spatiospectral data for use in underwater remote sensing. The FSI system is designed around a modular approach which utilizes separated illumination and detector units for reduction in common volume backscatter. The desired modularity and sensitivity have required novel optical and system design solutions. This paper details aspects of the FSI intended mission relevant to determination of system requirements, along with a description of the selected design approach and its expected performance.
