文摘
- •
A new Gerchberg–Saxton-like algorithm is proposed for phase retrieval.
- •
The introduction of gradient descent and weighting technique in the proposed algorithm guarantees better convergence in comparison to the Gerchberg–Saxton algorithm.
- •
Both simulation and optical experiments of DOE and CGH for holographic display are carried out to demonstrate the algorithm.
