Optimization of Phase-Only Computer-Generated Holograms Based on the Gradient Descent Method

Optimization of Phase-Only Computer-Generated Holograms Based on the Gradient Descent Method

The Gerchberg–Saxton (GS) algorithm is a Fourier iterative algorithm that can effectively optimize phase-only computer-generated holograms (CGHs). This study proposes a new optimization technique for phase-only CGHs based on the gradient descent method. The proposed technique evaluates the intensity...
