摘　　要：鬼成像,即关联成像,是近年来量子光学研究的前沿和热点之一,是基于量子纠缠或者经典光场涨落的关联特性,通过参考光场与目标探测光场之间的强度关联,非定域地获取目标物体信息的一种新型成像技术。鬼成像提供了一种运用常规手段难以获得清晰图像的方法,能够解决一些常规成像不易解决的问题。经过二十几年的发展,已被应用于军事、雷达探测和光学加密,未来还可进一步应用于病理分析、材料研究、生命科学和物质科学等领域。文中从鬼成像的历史起源开始,回顾其发展历程,介绍鬼成像的原理,分析影响鬼成像质量的因素,并对鬼成像系统中散斑结构与产生、重构方法和系统优化等方面进行阐述,同时简述了鬼成像技术在光学加密和边缘检测中的应用研究。The ghost imaging(GI),which is also named correlated imaging,is currently a hot topic in quantum optics.Based on the correlation of entanglement or field fluctuations,a clear image of a non⁃lo⁃calized object is obtained,at the idler path,by harnessing the intensity correlation between the signal beam and the idle beam.GI has huge values and extensive usages in optically harsh(difficult to be reached)or noisy environments.After more than two decades of development,GI has found its application in military,LIDAR,optical encryption,so on,and their future research on pathological analysis,material research and life sciences.By reviewing the development history of GI,the priciple of ghost imaging is in⁃troduced,the factors affecting the quality of ghost imaging are analyzed,and the progress of speckle gener⁃ation,reconstruction and optimization of GI system are described.Finally,the applications of GI in the optical encryption and the edge detection are demonstrated.
