Reconstruction régularisée basée sur un modèle non-linéaire de formation d'hologramme

Lensless microscopy is a robust and user-friendly ”low cost” imaging technique. It allows to recreate transmittance images (absorption and phase) of micro-objects. In recent years, important progress has been made in digital holography with the formalization of the image reconstruction problem as an inverse problem. To extend the field of applications to large, numerous, and/or phase objects, it is essential to consider a nonlinear hologram-image formation model, as well as to use a regularization adapted as best as possible to the a priori present in the object. We propose here an inverse problem method using a nonlinear hologram-image formation model, combining two regularizations.
