Abstract: Optical imaging apparatus and method of operating the same, where the apparatus includes optics configured to provide a first optical channel and a second optical channel through the optics, a two-dimensional image sensor optically coupled to the optics, the two-dimensional image sensor configured to receive a first optical signal from the first optical channel and provide a two-dimensional image, a one-dimensional image sensor assembly optically coupled to the optics and sharing a same line of sight, the one-dimensional image sensor assembly configured to receive a second optical signal from the second optical channel at a one-dimensional image sensor therein to provide an image with an overlapping coverage area in the two-dimensional image, and at least one processor configured to operate the two-dimensional image sensor and the one-dimensional image sensor assembly.

Abstract: A system simulates hyperspectral imaging data or multispectral imaging data for a simulated sensor. Blackbody radiance of real-world thermal imagery data is computed using a Planck function, which generates a simulated spectral hypercube. Spectral emissivity data for background materials are multiplied by a per-pixel weighting function, which generates weighted spectral emissivity data. The simulated spectral hypercube is multiplied by the weighted spectral emissivity data, which generates background data in the simulated spectral hypercube. Simulated targets are inserted the background data using the Planck function. The simulated spectral hypercube is modified, and then it is used to estimate a mission measure of effectiveness of the simulated sensor.
