Liquid lens based holographic camera for real 3D scene hologram acquisition using end-to-end physical model-driven network

Light: Science & Applications
With the development of artificial intelligence, neural network provides unique opportunities for holography, such as high fidelity and dynamic calculation. How to obtain real 3D scene and generate high fidelity hologram in real time is an urgent problem.

High-efficiency, broadband, and low-crosstalk 3D holography by multi-layer holographic-lens integrated metasurface

APL Photonics
Holographic display is considered the holy grail of photorealistic three-dimensional (3D) visualization technology because it can provide arbitrary wavefronts related to the essential visual cues of 3D images.

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

Simulated holographic three-dimensional intensity shaping of evanescent-wave fields [PDF]

, 2008
The size of bright structures in traveling-wave light fields is limited by diffraction. This in turn limits a number of technologies, for example, optical trapping.

Ferroelectric Liquid Crystal Compound Lens Based on Pancharatnam–Berry Phase

Crystals, 2022
We report a ferroelectric liquid crystal (FLC) compound lens based on the Pancharatnam–Berry (PB) phase. The phase of the FLC compound lens is an integration of polarization grating and a PB lens. Thus, when light passes through an FLC compound lens, the

Single-shot digital holographic microscopy based on computational telecentricity using a single-arm off-axis interferometer

ICT Express, 2018
We propose a single-shot digital holographic microscopy based on computational telecentricity with a single-arm off-axis interferometer (SA-OAI), which is composed of optical recording, computational compensation and retrieving processes.
