A Deep Learning Framework for Multi-Plane Computer-Generated Holography

Photonics
Multi-plane computer-generated holography is a key technology for enabling volumetric and near-eye displays. However, its widespread adoption remains constrained by the high computational cost of phase optimization and the persistent issue of axial ...

Critical point drying of brain tissue for X‐ray phase‐contrast imaging

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 759-768, May 2026.
X‐ray phase contrast tomography can efficiently image brain tissue at subcellular resolution. Critical point drying allows a gentle replacement of interstitial material by air, enhancing X‐ray phase contrast of the ultrastructural features.X‐ray phase‐contrast tomography can efficiently image brain tissue at subcellular resolution.

Phase and absorbance retrieval in X‐ray holographic microscopy under weak illumination using physics‐driven neural networks

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 794-805, May 2026.
A physics‐driven deep learning model enables single‐shot retrieval of 3D phase and absorbance from shot‐noise‐limited hard X‐ray holograms. Validated on both synthetic and experimental data, it provides robust reconstruction under weak illumination.X‐ray holographic microscopy is a three‐dimensional (3D) imaging technique for nanoscale‐resolution ...

U²-Net-Combined End-to-End Unsupervised Learning Method for Implementing Accurate Computer-Generated Phase-Only Hologram

IEEE Access
Holography is an emerging technology where phase-only spatial light modulator (SLM) is better than amplitude-only SLM because of its enhanced diffraction efficiency and rendering quality.

Improving reconstructions of digital holograms

, 2012
Digital holography is a two step process of recording a hologram on an electronic sensor and reconstructing it numerically. This thesis makes a number of contributions to the second step of this process. These can be split into two distinct parts: A) speckle reduction in reconstructions of digital holograms (DHs), and B) modeling and overcoming partial
