Claim Text:
1. Apparatus for use with a light source configured to direct non-spatially-coherent light toward an object, the apparatus comprising: an imaging system that comprises: an optical system for collecting a plurality of wavefronts, the plurality of wavefronts emanating from respective points of the object, as a result of the non-spatially-coherent light being directed toward the object, each of the plurality of wavefronts being composed of multiple spectral bands, each of the spectral bands having a respective amplitude, phase and polarization; a spectral imaging camera that comprises a plurality of detectors corresponding to the respective points of the object and configured to receive, from the optical system, the wavefronts emanating from the respective points; a modulator disposed along an optical path that passes between the object and the spectral imaging camera, the modulator being configured to individually modulate each of the wavefronts emanating from the respective points, by, individually, for each of the wavefronts: causing one or more spectral bands within a first portion of the wavefront that travels along the optical path to interfere with one or more spectral bands within a second portion of the wavefront that travels along the optical path, by applying an optical path difference to the first portion of the wavefront relative to the second portion of the wavefront that is equal for all of the spectral bands of the first portion of the wavefront; and a processing unit configured:
