| 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. |
