Angular resolution of images using photons having non-classical states

摘要

A method, apparatus, and system for improving the angular resolution of an image. A plurality of photon beams originating from a scene are received at a sensor system. Each of the plurality of photon beams is interfered with a corresponding source photon beam in a plurality of source photon beams to form a plurality of interference beams. Each of the plurality of source photon beams has a non-classical state. Fluctuations in a photon-number of the each of the plurality of source photon beams are reduced to within selected tolerances. An output signal is formed based on the plurality of interference beams. The output signal is configured for use in generating an image of the scene.

1. A method comprising:
receiving a plurality of photon beams at a sensor system, wherein the plurality of photon beams are from a far-field scene; wherein a first aperture receives a first photon beam in the plurality of photon beams and a second aperture receives a second photon beam in the plurality of photon beams; wherein the first aperture is physically separated from the second aperture; interfering each of the first photon beam and the second photon beam in the plurality of photon beams with a corresponding source photon beam in a plurality of source photon beams generated by a coherent source to form a plurality of interference beams, wherein each of the plurality of source photon beams has a non-classical state in which fluctuations in a photon-number of the each of the plurality of source photon beams is reduced to within selected tolerances; and forming an output signal based on the plurality of interference beams, wherein the output signal is configured for use in generating an image of the scene.
