WebJan 15, 2024 · Therefore, the issue of speckle noise in cylindrical holography needs to be solved further. In this paper, a deterministic gradient update is proposed for the speckle suppression of cylindrical holography. The proposed method is an optimization method for phase-only cylindrical hologram generation. The optimized hologram is achieved by ...
