Abstract
A system is provided comprising: a light field emanating from a scene and a positive imaging lens focusing light from the light field onto a DMD array. A first collector lens directs the spatially modulated light to a first photodetector having a spectral sensitivity to a first spectral band. The first photodetector senses the directed light from the first pixel-wise multiplication and produces a signal representing a first inner product between the light incident on the DMD and the first basis function for the first spectral band. A second collector lens directs the spatially modulated light to a second photodetector having a spectral sensitivity to a second spectral band. The second photodetector senses the directed light from the first pixel-wise multiplication and produces a signal representing a first inner product between the light incident on the DMD and the first basis function for the second spectral band.
