Abstract
Quantum imaging with undetected light (QIUL) leverages the quantum correlations of photon pairs generated via spontaneous parametric down-conversion (SPDC) to retrieve both amplitude and phase information of an object. This method enables illumination and detection at distinct wavelength ranges, utilizing advanced detection technology in the visible spectrum while probing the object at an exotic wavelength. Here, we experimentally demonstrate a QIUL technique incorporating Fourier off-axis holography within a hybrid-type induced-coherence nonlinear interferometer. Our approach reconstructs the amplitude and phase information of an object in a single shot using a wide-field configuration, presenting a viable alternative to multi-frame acquisition techniques such as phase-shifting holography.
