Comparison on wavefront aberration correction for laser beam propagating over saline water and sands
Wavefront aberration characterization and correction in laser beam propagating over saline water and sand was investigated in this paper. An experimental setup was built for wavefront aberration measurement and correction by an adaptive optics(AO) system. Based on the input-output data of the AO system, a model was established for the AO system and a closed-loop controller was built. Experimental results show that the laser beam propagating over sands surfers more severe wavefront aberration by the turbulence. After closed-loop AO correction, the variance of the spots displacement in the wavefront sensor is reduced by 28% forsaline water and 10% for sands. By doing this research, the feasibility of using close-loop AO systemsfor wavefront aberration correction in marine environment is investigated.
