Systems and methods for simultaneous multi-channel off-axis holography

An imaging system comprising:

• a light system having a plurality of light sources, each of the plurality of light sources configured to generate an illumination beam and a reference beam comprising coherent light having a common spatial coherence characteristic, and each of the plurality of light sources configured to generate the illumination and reference beams having a spatial coherence characteristic different than the spatial coherence characteristics of the other of the plurality of light sources;
• an illumination system configured to receive the illumination beams from the light system and propagate the illumination beams from the light system to a light output device to illuminate an object with the illumination beams;
• an optical system comprising a pupil, the optical system configured to receive a target beam of light reflected from the object and provide the target beam through the pupil to an optical imaging system;
• a reference system configured to receive the reference beams from the light system and propagate the reference beams to the optical imaging system;
• an optical imaging system configured to receive the reference beams from the optical system and the target beam and to combine the reference beams with the target beam to form a collective image representing the object, the collective image characterized as 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 plurality of reference beams and having spatial coherence information corresponding to the object;
• and
• an image sensor configured to capture the collective image of the object.
