Holographic Display System to Suppress Speckle Noise Based on Beam Shaping

Photonics, 2021
In this paper, a holographic system to suppress the speckle noise is proposed. Two spatial light modulators (SLMs) are used in the system, one of which is used for beam shaping, and the other is used for reproducing the image.
