Original Abstract Submitted

a snapshot hyperspectral imaging camera assembly and processing methods are provided that has a higher achievable resolution than a traditional snapshot imager. the camera assembly is compact and can be attached to the output port of any traditional benchtop microscope. this camera assembly has a relay lens that relays the fourier plane from the microscope onto a phase mask that encodes the spatial information of the target, and a spectral filter array that encodes the spectral information of the target. measurements are processed with a compressed sensing algorithm and an optimization algorithm to reconstruct a 3d hypercube from 2d intensity measurements.
