A design approach for developing a staring-dispersive infrared imaging spectroradiometer utilizing a fiber-optic image formatter to simultaneously capture, at rates greater then 100 Hz, 256 high-resolution spectral images of a 2D scene is described. Detailed performance analyses confirm that the spectral radiance within the image scene can be measured to high absolute accuracy. The proposed low-risk prototype, based on commercial off-the-shelf components to minimize the development risk, can be cost-effectively upgraded to a final field instrument through replaceable optical, calibration, and detector modules. Producibility of the design, as described by mechanical layouts and manufacturing drawings of the optical, fiber-optic, and dispersive elements, has been confirmed by independent component manufacturers. The rugged design is sufficiently compact for use in high-performance military aircraft, and can be applied to numerous civilian applications such as environmental cleanup, mineral surveys, vegetation monitoring, and combustion analysis.
