Robust Holographic Reconstruction by Deep Learning with One Frame

Photonics, 2023
A robust method is proposed to reconstruct images with only one hologram in digital holography by introducing a deep learning (DL) network. The U-net neural network is designed according to DL principles and trained by the image data set collected using ...

Multi-Object Deep-Field Digital Holographic Imaging Based on Inverse Cross-Correlation

Applied Sciences, 2023
To address the complexity of small or unique reconstruction distances in digital holography, we propose an inverse cross-correlation-based algorithm for the digital holographic imaging of multiplanar objects with a large depth of field. In this method, a
