Claim 0:
1. A method for forming a collective image, the method comprising:
receiving, at an imaging sensor, interaction light resulting from interaction between an illumination beam and an object, to form an image of an object on the imaging sensor, the illumination beam comprising light having a plurality of different spatial coherence characteristics; and
interfering at least a portion of the interaction light with a plurality of reference beams simultaneously, thereby forming a plurality of interference patterns imaged on the image sensor;
wherein each reference beam has a spatial coherence characteristic corresponding to one of the different spatial coherence characteristics; and
wherein the plurality of interference patterns combine with the image of the object to form the collective image on the imaging sensor, the collective image having a Fourier transform that includes a plurality of side lobe pairs in Fourier space, each side lobe pair comprising a side lobe and a complex conjugate of the side lobe formed opposite the side lobe about the center of the collective image, each side lobe corresponding to one of the reference beams and having spatial coherence information corresponding to the object.
