Speckle reduction method for phase-only hologram generation by double amplitude freedom Gerchberg-Saxton algorithm
A double amplitude freedom Gerchberg-Saxton (GS-DAF) algorithm is proposed. The amplitude constraints in iterations are relaxed by both the combined amplitude constraint and the support constraint. Enhanced reconstructions with less speckle noise have been achieved.
