Paper Abstract

The receiving signal-noise ratio and image quantity on laser coherent detection is effected by atmospheric turbulence. A turbulence generator has been designed and built for laboratory testing. There is a n laser coherent detection system named the Phase Shift System. The effects of the generated turbulence on optical propagation are directly measured by sensing the perturbed wavefront phase. By using the generator, we can observe the wavefront phases and estimate the phase structure function.
