Abstract
The vector 3D Gerchberg-Saxton (G-S) phase retrieval algorithm utilizes the properties of three-dimensional Fourier transform to perform more accurate calculations on the tiny light field, but this algorithm has low light intensity utilization and serious crosstalk in multi-plane holographic display. This paper proposes a modified vector 3D G-S algorithm, which improves image clarity by jointly adjusting the intensity of the reconstructed light field, and sets dynamic weights on each target plane to improve the image uniformity. In order to verify effectiveness of the modified algorithm, simulation comparison experiments are conducted on binary images and grayscale images in the case of 2-4 target imaging planes. The results show that the modified algorithm improves the clarity and uniformity of multi-plane image without slowing down the convergence rate, which is helpful for applications such as micro-nano processing that require high image quality.
