Image reconstruction from in-line holograms using inverse problems recipes: tutorial

Autor: Momey, Fabien, Denis, Loïc, Olivier, Thomas, Brault, Dylan, Berdeu, Anthony, Fournier, Corinne

We present our tutorial [1] for building inverse problems based image reconstruction strategies in digital in-line holography (DH), starting from the identification of the connections with the well known alternated projections strategies. In-line DH

International audience; In-line digital holography is a simple yet powerful tool to image absorbing and/or phase objects. Nevertheless, the loss of the phase of the complex wavefront on the sensor can be critical in the reconstruction process. The si

International audience; We present a new 3D lens-free microscope for large 3D biological samples and a dedicated reconstruction algorithm based on the Fourier diffraction theorem as used in standard diffractive tomography [1, 2]. It uses a regularise
