Title: System for outputting a spectrum of light of a scene having optical detectors to receive light of different spectral transmittance from respective filters

Abstract

Technologies pertaining to a compressive sensing snapshot spectrometer are described herein. Light is focused through an array of filters onto an array of optical detectors by way of an optical objective. Each detector in the array receives light from a single respective filter in the filters. Each filter in the filters has a spectral transmittance function that overlaps a spectral transmittance function of at least one other filter. A compressive sensing algorithm is executed over outputs of the detectors based upon the known spectral transmittance functions of the filters. Based upon the execution of the compressive sensing algorithm, intensity values of the light are identified for a number of spectral bins that is greater than a number of detectors in the array.
