鬼成像是指由同一个光源发出的两束光，其中一束光称为信号光，通过物体照射在探测器上，另一束光称为闲置光，光路上不包含任何物体，最后对这两束光进行符合计数，通过符合测量可以得到物体的像。本文在基于轨道角动量的量子成像理论基础上，首先介绍大气湍流对成像质量产生的影响，然后采取纠锗编码的方法来抑制湍流的影响。本文用LabView软件进行仿真，由仿真结果表明，采用（7，4）线性分组码之后，成像质量显著提高，有效减小了湍流的影响。

Ghost imaging is a technique that forms an image of an object by measuring two correlated optical fields. The path including the object is usually called ＇signal arm＇ , and the other one is named ＇idler arm＇ This paper is based on Orbital Angular Momentum （OAM） of quantum imaging. First, we introduce the effect of turbulence on ghost imaging, and then we use error correction of coding to restrain it. The simulation results show that we can significantly improve the quality of the imaging by using （7,4） hnear block code.
