Zooming algorithms for Digital Holography
Digital Holography is an imaging modality made up of two parts: (i) Recording an interference pattern on a CCD, where an object wave field and a known reference wave are coincident and extracting the complex object wave field from this interference pattern and (ii) Replaying or reconstructing the hologram on a computer by simulating the propagation of ...

Vectorial Diffractive Neural Metasurfaces for Multiplexed Synthesis of Optical Skyrmions
A three‐layer Jones‐matrix‐based vectorial diffractive neural network enables compact, passive, and multiplexed synthesis of optical skyrmions and bimerons. By mapping distinct Gaussian‐beam input channels to coaxial orbital‐angular‐momentum and polarization states, the device generates up to 16 topological vector textures with high mode purity, robust

Backscatter digital holography of microparticles
This work investigates a method for digital holographic imaging of microparticles. Traditional digital holographic techniques use a particle's forward scattered light to form the hologram, whereas here we use the backscattered light. Images of a particle are then computationally reconstructed from the backscatter hologram, and several examples of such ...

Multiwavelength digital holography with spatial phase shifting on moving objects
Paper DM3I.6, 3 S.It was not possible so far to characterize moving objects using interferometric techniques. We present an implementation where the 3D profiles of objects moving at velocities up to 100 mm/s are obtained by digital ...
