Application of the Phase Recovery Algorithm Based on the Parallel Architecture in the Holographic Projection Technology

摘要

Compared with conventional display technology, holographic projection technology has outstanding advantages. The phase retrieval algorithm is a key image processing algorithms in holographic projection technology. The constringency speed and precision of these algorithms need to be raised. The performance of the algorithms above are not satisfactory, sometimes they cannot even guarantee that the iterative process converges to the correct solutions. Then, this paper proposes a parallel architecture based on the phase recovery algorithm-Parallel Gerchberg-Saxton with Genetic Algorithm (PGSGA). Simulation has proved that the proposed algorithm PGSGA is better in convergence rate and the restoration quality by testing gray-scale image.
