摘　　要：关联成像是通过分析光场的二阶关联特征实现非定域成像,该成像方式为光学成像技术的发展开启了新的篇章.随着关联成像的发展,高阶关联成像在提高图像对比度方面得到广泛关注.本文基于三阶相干理论,提出了图像的拼接方案.该方案将2个空间分离的物体分别放置于2路不同的信号光路中,通过探测光场的三阶关联,实现非定域的鬼像拼图.数值模拟与实验结果均表明:通过采用热光三阶关联技术对目标物体进行拼图,可以重构出物体的完整形态.Correlation imaging achieves non-local imaging by analyzing the second-order correlation characteristics of the light field,which brings a new chapter to the development of optical imaging technology.With the development of correlated imaging,high-order correlated imaging has received widespread attention in improving image contrast.Based on the theory of thermal light third-order coherence,this paper proposed a ghost imaging stitching scheme.The two spatially separated objects were placed in two signal light paths,and three detectors were used to detect three reference light paths.The non-local image stitching was achieved by detecting the third-order correlation of the light field.Both numerical simulation and experimental results indicated the feasibility of this scheme,which had potential application prospects in fields such as information transmission and secure encryption.
