关联成像是一种基于光场高阶关联获取物体信息的新型主动成像机制,具有高灵敏、抗干扰等特点,在生物医学、遥感成像等领域有广阔的应用前景。关联成像需要多次采样来重构物体图像,成像过程需要一定的时间,在此期间物体和成像系统的相对运动会导致图像质量退化。如何提升对运动物体的成像能力是关联成像走向应用需要解决的关键问题之一。简要回顾了关联成像的基本概念,详细介绍了运动物体关联成像的原理方法、发展历程及研究现状,比较了所述技术所适用的场景并展望了其发展趋势。

Ghost imaging is a novel active imaging technique in which the information of the object is obtained based on high-order correlation of light fields. It has the characteristics of high sensitivity and anti-interference, and has broad application prospects in biomedicine, remote sensing imaging, and other fields. Ghost imaging requires multiple samplings to reconstruct the object image, and the imaging process takes a certain time, during which the relative motion between the object and the imaging system will lead to the degradation of image quality. How to improve the performance of imaging for moving objects is one of the key problems to be solved in the application of correlation imaging. In this paper, the basic concepts of ghost imaging are briefly reviewed; the principle of method, development, and current status of ghost imaging for moving objects are introduced. The applicable scenarios of the proposed technique are compared and the development trend is forecasted
