Convolutional neural network (CNN) has great potentials in holographic reconstruction. Although excellent results can be achieved by using this technique, the number of training and label data must be the same and strict paired relationship is requir

An approach to generate the tunable fractional vector curvilinear beams (VCBs) was proposed. The scheme is based on the vector optical field generator (VOFG) system, where the two orthogonal polarized scalar curvilinear beams (SCBs) are generated to

We theoretically propose and experimentally verify a method to generate new polycyclic beams, namely concentric perfect Poincaré beams (CPPBs), by using an encoded annular phase mask. The proposed beams consisting of multiple polarization structured

In this paper, we propose a new algorithm based on deep learning to reduce the speckle noise for coherent imaging without clean data. By learning the common information, namely the clean image, from paired noisy holographic reconstructed images, the

A method is proposed for generating noncanonical perfect vortex beams (PVBs) based on a theory deduced from the definition of topological charge. Varying the phase gradient of the light field in the region of the decomposed integral provides arbitrar

We propose a Bessel-like composite vortex filter to perform high-contrast and power-controlled anisotropic edge enhancement with shadow-effect-free and low background noise. The background noise, which is commonly found and strongly decreases the fil
