phase retrieval is the assumption that the sample interacts sufﬁciently weakly with the X-rays such that the relation (1) can be linearized with respect to the phase and absorption images and . Neglecting higher-order contributions in the components of the refractive index and rearranging, this leads A general mathematical framework and recovery algorithm is presented for the holographic phase retrieval problem. In this problem, which arises in holographic coherent diffraction imaging, a "reference" portion of the signal to be recovered via phase retrieval is a priori known from experimental design. Holograms computed using our "learned hardware-in-the-loop phase retrieval" eliminates severe aberrations and show an improved quality, enhanced resolution and remarkable contrast, with black regions truly being black as shown below. We achieve all of this in a holographic display, perhaps for the first time to the best of our knowledge.

In this problem, which arises in holographic coherent diffraction imaging, a "reference" portion of the signal to be recovered via phase retrieval is a priori known from experimental design. A general mathematical framework and recovery algorithm is presented for the holographic phase retrieval problem. In this problem, which arises in holographic In the computational imaging community, many attempts have been made in solving holographic phase retrieval using references, among which has been very successful. Motivated by the reference design for holographic phase retrieval, we are trying to explore a way to design references for general phase retrieval. A general mathematical framework and recovery algorithm is presented for the holographic phase retrieval problem. In this problem, which arises in holographic coherent diffraction imaging, a "reference" portion of the signal to be recovered via phase retrieval is a priori known from experimental design. Phase retrieval is the art of acquiring this information which is crucial in surface reconstruction, microscopy, location detection and depth measurements.
