Abstract:Orbital angular momentum (OAM) holography has become a promising technique in information encryption, data storage and opto-electronic computing, owing to the infinite topological charge of one single OAMmode and the orthogonality of different OAM modes. In this paper, we propose a novel OAM hologramgeneration method based on a densely connected U-Net (DCU), where the densely connected convolutionblocks (DCB) replace the convolution blocks of the U-Net. Importantly, the reconstruction process of theOAM hologra… Show more
