Abstract
We report the all-optical and twin-image-free reconstruction of inline holograms using diffractive networks. Our numerical results reveal that these diffractive network designs, when properly trained using error back-propagation algorithms, generalize very well to reconstruct new, unseen holograms at the speed of light propagation, without any external power source (except the illumination light). These diffractive hologram reconstruction networks also exhibit improved power efficiency and extended depth-of-field. With their passive operation and orders-of-magnitude faster reconstruction speed than digital hologram reconstruction systems, diffractive networks can find numerous applications in holographic imaging and display-related applications.
