Description

TECHNICAL FIELD

[0001] The present application relates to the field of atmospheric turbulence simulation, in particular to a layered atmospheric turbulence simulation device. BACKGROUND

[0002] Various activities of human beings and nature will generate many turbulence vortexes in the atmosphere. Atmospheric turbulence will cause random changes in the refractive index of the light beam, thereby destroying the coherence of the light field, and macroscopically manifesting as atmospheric turbulence effects such as phase fluctuation of the propagating light beam, angle of arrival fluctuation, light intensity flicker, beam drift, etc. These effects become more and more serious as the propagation distance increases or the turbulence intensity increases. From the perspective of communication, atmospheric turbulence will cause an increase in the bit error rate, communication interruption and other adverse effects. For other components of the space optical communication system, such as the tracking and pointing system and the adaptive optical system, the system parameters are closely related to atmospheric turbulence. In order to improve the performance of the space optical communication system, it is necessary to conduct special research on the propagation characteristics of the light beam in the turbulent atmosphere and find ways to overcome the effects of atmospheric turbulence, so as to ultimately achieve stable communication.

DETAILED DESCRIPTION

[0030] The drawings in the present application are not strictly drawn according to the actual proportions, and the specific sizes and quantities of various structures can be determined according to actual needs. The drawings described in the present application are only schematic structural diagrams.

[0031] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without any creative effort fall within the scope of protection of the present application.

[0033] Atmospheric turbulence is an important form of atmospheric motion. The activities of human beings and nature, and the radiation of the sun can cause small changes in atmospheric temperature, which generates many turbulence eddies in the atmosphere, causing random changes in atmospheric density, resulting in unordered, non-deterministic changes in atmospheric refractive index. The changes in this physical quantity are irregular in space and time. The small changes in atmospheric refractive index are similar to the generation of a small "lens" in the atmosphere. The size of the "atmospheric lens" is approximately equal to the scale of the turbulence vortex, and the order of magnitude of the change is the order of magnitude of the wavelength of light (10 -6 ). The cumulative result leads to significant non-uniformity of the atmospheric refractive index profile, thereby causing random fluctuations in the wavefront of the light beam transmitted in the turbulent atmosphere, thereby causing a series of atmospheric turbulence effects of light transmission such as beam jitter, intensity fluctuation, beam expansion, and image point jitter. Atmospheric turbulence will cause random changes in the refractive index of the light beam, thereby destroying the coherence of the light field, and macroscopically manifesting as phase fluctuations, angle of arrival fluctuations, light intensity flicker, beam drift, and other atmospheric turbulence effects of the propagating light beam. These effects become more and more serious as the propagation distance increases or the turbulence intensity increases. From the point of view of communication, atmospheric turbulence will cause an increase in the bit error rate, communication interruption, and other adverse effects. For other components of the space optical communication system, such as the tracking and pointing system and the adaptive optical system, the system parameters are closely related to atmospheric turbulence. In order to improve the performance of the space optical communication system, it is necessary to conduct special research on the propagation characteristics of the light beam in the turbulent atmosphere, find methods to overcome the effects of atmospheric turbulence, and ultimately achieve stable communication. Because long-distance laser atmospheric transmission experiments are time-consuming and laborious and have poor repeatability, there is an urgent need for an atmospheric turbulence simulator that can simulate atmospheric turbulence disturbances in order to carry out corresponding experiments in the laboratory.
