Simulation of Partially Coherent Optical Atmospheric Turbulent Transmission Based on LC-SLM
In this paper, liquid crystal on Silicon Modulator (LC-SLM) is applied to laser transmission system. The beam parameters of the initial light source are adjusted by the phase modulation principle of LC-SLM to simulate the propagation of partially coherent light with different coherence in atmospheric turbulence. The centroid drift of a partially coherent beam propagating in turbulent atmosphere is studied. By comparing the drift of beams with different coherent lengths in turbulence, the results show that the drift of partially coherent beams is less affected by turbulence disturbance.
