Compact holographic sound fields enable rapid one-step assembly of matter in 3D

Science Advances, 2023
Acoustic waves exert forces when they interact with matter. Shaping ultrasound fields precisely in 3D thus allows control over the force landscape and should permit particulates to fall into place to potentially form whole 3D objects in “one shot.” This ...

Deep learning-based incoherent holographic camera enabling acquisition of real-world holograms for holographic streaming system

Nature Communications, 2023
While recent research has shown that holographic displays can represent photorealistic 3D holograms in real time, the difficulty in acquiring high-quality real-world holograms has limited the realization of holographic streaming systems.

Tunable liquid crystal grating based holographic 3D display system with wide viewing angle and large size

Light: Science & Applications, 2022
As one of the most ideal display approaches, holographic 3-dimensional (3D) display has always been a research hotspot since the holographic images reproduced in such system are very similar to what humans see the actual environment.
