1. A method comprising:
uniformly illuminating a scene within a field-of-view of an emitter;
having a receiver comprising a plurality of detectors;
selectively sampling a subset of the plurality of detectors in accordance with compressive sensing techniques;
capturing depth and intensity measurements by each of the subset of the plurality of detectors, each detector capturing depth and intensity information corresponding to a subset of the field-of-view; and
generating, by a processor, images of the scene in accordance with an output from the subset of the plurality of the detectors, the images providing a depth and intensity image corresponding to the field-of-view of the emitter.
