Description

Technical Field

[0001] The invention relates to the technical field of atmospheric turbulence simulation, and in particular to a layered atmospheric turbulence simulation device. Background Art

[0002] Various activities of humans and nature will generate many turbulent vortices 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. Macroscopically, it manifests itself as atmospheric turbulence effects such as phase fluctuations, arrival angle fluctuations, light intensity flickering, and beam drift of the propagating light beam. These effects become more serious as the propagation distance increases or the turbulence intensity increases. From a communication perspective, atmospheric turbulence can cause adverse effects such as increased bit error rate and communication interruption. For other components of the space optical communication system, such as the tracking and aiming system and the system parameters of the adaptive optical system 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 ways to overcome the atmospheric turbulence effects, and ultimately achieve stable communication.

[0030] The drawings in the present invention are not drawn strictly according to the actual scale, and the specific size and quantity of each structure can be determined according to actual needs. The drawings described in the present invention are only schematic diagrams of the structures.

[0031] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. The words "include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Inside", "outside", "up", "down", "far", "near", "front", "back" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0033] Atmospheric turbulence is an important form of atmospheric motion. Various human and natural activities, as well as solar radiation, will cause slight changes in atmospheric temperature, generate many turbulent vortices in the atmosphere, cause random changes in atmospheric density, and lead to disordered and non-deterministic changes in the atmospheric refractive index. This change in physical quantity is irregular in space and time. Slight changes in the atmospheric refractive index are similar to the creation of small "lenses" in the atmosphere. The size of the "atmospheric lens" is approximately equal to the size of the turbulent vortex, and its magnitude of change is on the order of the wavelength of light (10 -6 ), the cumulative result leads to obvious inhomogeneity of the atmospheric refractive index profile, which causes 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 fluctuations, 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, which is manifested macroscopically as atmospheric turbulence effects such as phase fluctuations, arrival angle fluctuations, light intensity flickering, and beam drift of the propagating light beam. These effects become more and more serious with increasing propagation distance or turbulence intensity. From a communication perspective, atmospheric turbulence can cause adverse effects such as increased bit error rate and communication interruption. For other components of the space optical communication system, such as the tracking and aiming system and the system parameters of the adaptive optical system are closely related to atmospheric turbulence. In order to improve the performance of the space optical communication system, it is necessary to carry out special research on the propagation characteristics of the light beam in the turbulent atmosphere, find ways to overcome the atmospheric turbulence effects, and ultimately achieve stable communication. Since long-distance laser atmospheric transmission experiments are time-consuming, labor-intensive and have poor repeatability, people in scientific research and engineering design are in urgent need of atmospheric turbulence simulators that can simulate atmospheric turbulence disturbances so that corresponding experiments can be carried out in the laboratory.

[0034] At present, there are many atmospheric turbulence simulation devices at home and abroad, including hot wind atmospheric turbulence simulation devices and forced convection atmospheric turbulence simulation devices. However, most of them are single-layer fixed turbulence simulation generators, and there is no experimental device for atmospheric turbulence with multi-layer structure.
