关联成像及其应用研究进展

Correlated Imaging and Its Applications

关联成像源于物理学领域的2个具有里程碑意义的事件:一个是20世纪初爱因斯坦-波多尔斯基-罗森佯谬(EPR佯谬)引发的量子非局域性的讨论,另一个是20世纪50年代美国科学家Hanbury Brown和Twiss实验(HBT实验)引发的对光场高阶干涉机理的探索.从20世纪90年代中期因有学者预言"鬼衍射"这一违反直觉和经验的现象而引起学界的广泛兴趣开始,到现今进入实际应用领域,中间已经过四分之一世纪的研究历史.从关联成像的历史起源开始,回顾它的发展历程,介绍其在光学相干和偏振领域、单像素成像、物体的复值获取、超越经典分辨率、X射线衍射成像、激光雷达领域,以及大气湍流环境下的应用,简述关联成像带给这些领域的突破和进展.

Correlated imaging originates from two landmark events in the field of physics.One is the discussion of quantum nonlocality triggered by EPR paradox in the beginning of last century,and the other is the exploration of highorder interference mechanism induced by HBT experiments in the 1950s.In the mid90s of last century,some scholars predicted the existence of“ghost diffraction”,a counter intuitive phenomenon.By now,it ghost imaging has entered practical applications,and a quarter century of its research history has passed.Begin by reviewing the development history of correlated imaging,we briefly introduce its applications in the fields of optical coherence and polarization,singlepixel imaging,complex value acquisition of objects,supper resolution imaging,X ray diffraction imaging,lidar imaging,and imaging in atmospheric turbulence.
