Abstract:
A phase-locking system based on the Gerchberg-Saxton algorithm is discussed. A global optimization strategy for retrieving phase information is proposed. A dimension reduction technique based on the block structure principle is considered. The system is simulated numerically for different configurations of phased channels.
Keywords:multichannel laser systems, Gerchberg-Saxton algorithm, phase-locking, global optimization, multiaperture wave front sensor.
