Abstract:Due to the loss of phase information in images captured by intensity-only measurements, the numerical reconstruction of inline digital holographic imaging suffers from the undesirable twin-image artifact. This artifact presents as an out-of-focus conjugate at the virtual image plane and reduces the reconstruction quality. In this work, we propose a diffusion-based generative model that eliminates such defocus noise in single-shot inline digital holography. The diffusion-based generative model learns the implic… Show more
