摘要

Laser beam propagating through the atmosphere is distorted by atmospheric turbulence and platform vibrations, leading to the reduction of received signals, beam pointing error, and bit-error rate (BER) degradation. Mathematical models of atmosphere and platform vibrations were developed simultaneously to simulate the actual laser communication. A realistic wavefront distortion generated by the Kolmogorov spectrum and McGlamery algorithm was applied with a liquid crystal spatial light modulator (SLM). A disturbance signal implemented by a two-dimensional piezoelectric steering mirror is applied to represent the platform jitter. Experimental results demonstrate how signal to noise ratio (SNR), BER and pointing error change with the increase of atmospheric turbulence strength and vibration spectrum bandwidth. This paper presents the modeling and measurement of effects of atmospheric turbulence and platform jitter. The distortion compensation and tracking techniques can be tested based on the system.
