Photon-counting digital holography under ultraweak illumination.
Digital holography based on photon counting under ultraweak illumination was demonstrated. A hologram was recorded with two-dimensional scanning of an optical fiber connected to a single-photon counting detector under an illumination of 43 photons per second, and the object image was clearly reconstructed in a computer from the hologram. The dependence of hologram quality on the illumination light intensity was estimated from the contrast and phase deviation of interference fringes obtained by photon-counting measurements.
