论文摘要
Ghost Imaging(GI)是一种非常规的成像方法,它通过将一系列已知的照明模式与总反射(或传播)强度相关联,从而检索对象的图像。我们在这里演示了一个方案,该方案可以删除了解对象上的事件模式的基本要求,从而使GI通过浑浊介质无创地图像对象。作为实验性证明,我们将一组模式投射到隐藏在浑浊介质中的对象,该对象扰乱了照明,使落在对象上的模式完全未知。从理论上讲,我们证明该物体的空间频率在GI的测量中保留了,即使丢失了对象和照明的空间信息。然后使用相检索算法重建图像。
Ghost imaging (GI) is an unconventional imaging method that retrieves the image of an object by correlating a series of known illumination patterns with the total reflected (or transmitted) intensity. We here demonstrate a scheme which can remove the basic requirement of knowing the incident patterns on the object, enabling GI to non-invasively image objects through turbid media. As an experimental proof, we project a set of patterns towards an object hidden inside turbid media that scramble the illumination, making the patterns falling on the object completely unknown. We theoretically prove that the spatial frequency of the object is preserved in the measurement of GI, even though the spatial information of both the object and the illumination is lost. The image is then reconstructed with phase retrieval algorithms.
