摘要: 研究了一种可以在湍流信道下自适应成像的鬼成像系统。系统利用可以模拟强起伏和弱起伏湍流的Gamma-Gamma分布来模拟湍流，虽然鬼成像可以在湍流下进行成像，但是大多数研究没有研究不同波长激光和采样率在不同湍流下的成像。本研究在采用不同波长的激光的基础上，测试不同的采样率在不同强弱湍流下的性能，并且通过闪烁指数计算了大气折射率结构常数。通过峰值信噪比和误比特率评价成像质量，得到不同模型的成像规律，为进一步的自适应鬼成像算法提供了新的模型。
Abstract: We investigate a ghost imaging system that can image adaptively under turbulent channels. The system utilizes a Gamma-Gamma distribution that can simulate strong and weak undulating turbu-lence to simulate the turbulence, and ghost imaging can be imaged under turbulence, but most studies do not study the imaging of different wavelength laser under different turbulence, and do not combine with the sampling rate. In this research, we test the performance of different sampling rates under different strengths of turbulence based on the use of different wavelengths of the laser. Finally, we calculate the refractive index structure constant by scintillation index. The imaging quality is evaluated by PSNR and BER, and the imaging law of different models is obtained, which provides a new model for further adaptive ghost imaging algorithms.
