Resolution Enhancement of Spherical Wave-Based Holographic Stereogram with Large Depth Range

Applied Sciences, 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

Curved Computer-Generated Integral Imaging Based on Backward Ray-Tracing Technique

IEEE Photonics Journal, 2023
In traditional computer-generated integral imaging (CGII) methods, the generated elemental image array (EIA) is flat, and it doesn't fit for curved integral imaging (II) systems. Here, a curved CGII method was proposed for curved II system. In the
