Holographic Lens Resolution Using the Convolution Theorem. [PDF]
Polymers (Basel), 2022 The similarity between object and image of negative asymmetrical holographic lenses (HLs) stored in a low-toxicity photopolymer has been evaluated theoretically and experimentally. Asymmetrical experimental setups with negative focal lengths have been used to obtain HLs.

GRIN-lens-based in-line digital holographic microscopy
Applied Optics, 2023 In-line digital holographic microscopy (DHM) provides three-dimensional images with large fields of view and depths of field and micrometer-scale resolution, using a compact, cost-effective, and stable setup. Here, we develop the theoretical background and experimentally demonstrate an in-line DHM based on a gradient-index (GRIN) rod lens. In addition,

Metasurface-Based Holographic Display With All-Dielectric Meta-Axilens
IEEE Photonics Journal, 2021 In a classical metasurface-based holographic display system, a clear holographic reconstruction image can be obtained only in the back-focal-plane of the lens. However, when the receiving plane deviates from the focal plane, the reconstructed holographic
