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.

Holographic Zoom System With Large Focal Depth Based on Adjustable Lens
IEEE Access, 2020 In this paper, we propose a holographic zoom system based on two adjustable lenses. Different from the traditional holographic system, a digital conical lens and a liquid lens are used as the zoomable lenses.

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
