描述
This product can quickly and quantitatively simulate the influence of atmospheric turbulence when the beam is transmitted in the atmosphere. It can simulate the effects caused by atmospheric turbulence when the beam is transmitted in the turbulent atmosphere: light intensity flicker (under limited aperture reception conditions), arrival angle undulation, beam propagation, spot drift, optical phase distortion and beam coherence degradation and other effects). The input parameters are configurable, and parameters such as transmission distance, refractive index structure constant, atmospheric coherence length can be set, and the output results can be monitored. It can be widely used in various types of laser system function verification and performance testing in atmospheric environment.
The liquid crystal atmospheric turbulence simulator can simulate the main effect characteristics of laser transmission in the earth’s atmospheric environment, such as: light intensity flickering, angular undulation and spot drift; The input parameters can be configured, and parameters such as altitude, elevation angle, transmission distance, time and location can be set, and the output results can be monitored and compared with theoretical values. It can be widely used for functional verification and performance testing of various types of atmospheric channel laser systems.
