Improvement of wavefront shaping based on AO algorithm

The wavefront shaping technology in the light field control solves the problem of coherent light focusing through the disordered scattering medium and simplifies the experimental device with iterative optimization method to achieve the purpose of strengthening the control of diffuse light.AO algorithm is introduced to process the incident wavefront to improve the wavefront shaping technology.In the experiment,compared with swarm intelligent optimization algorithms such as standard particle swarm optimization(PSO) and grey wolf algorithm(GWO),the improved wavefront shaping technology of AO algorithm has better optical focusing ability.The research shows that compared with PSO and GWO,the wavefront shaping technology imp roved by AO algorithm can obtain higher target light intensity and better speckle focusing effect.
