研究目的
Investigating the reciprocity of atmospheric channels in optical communication systems to provide a parameter reference for adaptive optics system design.
研究成果
The experimental results demonstrate strong reciprocity in atmospheric channels, with a correlation coefficient mostly above 0.80. This finding supports the feasibility of using adaptive optical techniques in optical communication systems and key extraction processes.
研究不足
The study is conducted under weak turbulence intensity, and the influence of stronger turbulence on channel reciprocity is not explored. Additionally, the experiment's transmission distance is limited to 865 m.
1：Experimental Design and Method Selection:
The study constructs a two-way atmospheric turbulent optical channel instantaneous fading correlation measurement system based on the theory of instantaneous fading correlation.
2：Sample Selection and Data Sources:
The experiment uses a transceiving integrated optical antenna at both ends, with a telescope diameter of 80 mm and a 1064 nm laser.
3：List of Experimental Equipment and Materials:
Includes a telescope, 1064 nm laser, detector, and camera for image acquisition.
4：Experimental Procedures and Operational Workflow:
The experiment involves transmitting light waves through an atmospheric turbulence channel, capturing continuous spot images at 1000 frames per second, and analyzing the gray value of each frame.
5：Data Analysis Methods:
The correlation coefficient of the instantaneous fading is calculated using the normalized cross-correlation function of the received signals at both ends.
