Sažetak
Holography is a powerful imaging technique that enables recording and retrieving the amplitude and phase information about an object. In this work, we report holography based on quantum light sources. Recently, holograms based on polarization-entanglement and phase-shifting were recorded by EMCCD. The method based on EMCCD required thresholding (to be sensitive to single photons) and selection of spatial correlations (to exclude noise signal). Another method for recording holograms with single photons based on image intensifier and photosensitive array was also recently reported. Usually, the second order correlation function g2(0) is used as a tool for the characterization of the photon source. However, in these holographic experiments no such measure was given. Due to theoretical disputes about the number phase uncertainty relation, it is of profound importance to use characterized light source for acquisition of quantum holograms. Successful hologram recording with well-defined number of photons should preserve the phase and amplitude information. Here, we present an approach for recording holograms based on heralded single-photon source and detection by photon-counting detectors (PCD). Holograms were recorded by 2D scanning of PCD in the image plane of the setup. Along the scanning PCD, four additional PCDs were used simultaneously for characterization. Multichannel coincidences could be taken employing time-tagging module with jitter resolution below avalanche photodiodes. As a source of heralded single-photons a nonlinear periodically poled potassium titanyl phosphate was used and we measured g2(0) = 0.00440(1) as one of the best values reported so far. We discuss phase and amplitude reconstruction of holograms of real objects taken with heralded photons in terms of fundamental quantum randomness and single-photon perspective.
