WebFeb 15, 2024 · The random phase method and quadratic phase method are most widely used in the generation of non-iterative phase holograms. However, the former leads to the reconstruction being severely disturbed by speckle noise, with serious loss of detailed information, and the latter leads to the reconstruction being contaminated with ringing … WebApr 17, 2024 · A fast and non-iterative method for generating a phase-only hologram, hereafter referred to as the patterned-phase-only hologram (PPOH), is reported in this paper. Briefly, a phase mask with a periodic phase pattern is added to the source image, and converted into a hologram.
Optimized random phase tiles for non-iterative hologram generation
WebFeb 7, 2024 · The Gerchberg–Saxton (GS) algorithm is a widely employed algorithm for the calculation of a phase-only hologram (POH). However, the POH that can strictly satisfy the amplitude constraints on the object and the holographic plane may not exist or be obtained, resulting in speckle noise and reduction of the reconstruction quality.
