摘　　要：为了探讨光场的高阶关联对于切向运动目标鬼成像的影响,将热光高阶强度涨落鬼成像理论应用于切向运动目标鬼成像的研究中,并对所得结果进行了数值模拟和仿真实验,获得了相关仿真图像。结果表明,采用高阶强度涨落关联理论研究切向运动目标鬼成像,随着参考光束的阶数增加,光场的高阶关联将会极大地增加背景涨落的噪声,导致图像重建质量变差,而信号光束的阶数增加对成像质量影响较小,所以最低阶的鬼成像质量最好。In order to investigate the impact of light field high-order correlation on the tangential moving target ghost imaging, high-order background-subtracted ghost imaging theory can be applied. Some numerical simulations and experiments are carried out, and the relevant simulated images are obtained. In this study of tangential moving targets ghost imaging based on the high-order background-subtracted ghost imaging theory, the results show that the high-order correlation of the light field inereases the background fluctuation noise when the reference beam order increases, and the quality of image reconstruction deteriorates. Moreover, the increase of the signal beam order has little effect on the image quality. So the best quality can be obtained by the lowest-order ghost imaging.
