Resolution Enhancement of Spherical Wave-Based Holographic Stereogram with Large Depth Range
Applied Sciences (Switzerland), 2021 The resolution-priority holographic stereogram uses spherical waves focusing on the central depth plane (CDP) to reconstruct 3D images. The image resolution near the CDP can be easily enhanced by modifying three parameters: the capturing depth, the pixel

Optical Metasurface‐Based Holographic Stereogram [PDF]
Advanced Optical Materials, 2020 AbstractHolographic stereography providing binocular depth cues is one of the most promising technologies for 3D displays. However, conventional holographic stereograms based on micrometer‐scale pixels suffer from multiple diffraction orders and narrow viewing angles.

Generating Multi-Depth 3D Holograms Using a Fully Convolutional Neural Network. [PDF]
Adv Sci (Weinh)This work introduces the forward–backward‐diffraction framework for computing multi‐depth diffraction fields and the layer‐by‐layer replacement method for handling occlusion relationships. When combined with a fully convolutional neural network, it generates multi‐depth holograms with excellent depth focusing and corrects occlusion relationships.
