论文摘要
提出了一种相敏的显微镜技术,并证明采用了自发参数下转换中固有的动量相关性。一个相关对的一个光子聚焦在微观目标上,而另一个则在傅立叶平面中测量。这提供了对目标撞击目标的每个光子的照明位置和角度的知识,从而使后期制作的完整后期控制控制了用于形成图像的照明角度。这种方法的多功能性通过不对称的照明和差异相比成像显示,而没有任何光束块或运动部件。
A phase-sensitive microscopy technique is proposed and demonstrated that employs the momentum correlations inherent in spontaneous parametric down-conversion. One photon from a correlated pair is focused onto a microscopic target while the other is measured in the Fourier plane. This provides knowledge of the position and angle of illumination for every photon striking the target, allowing full post-production control of the illumination angle used to form an image. The versatility of this approach is showcased with asymmetric illumination and differential phase contrast imaging, without any beam blocks or moving parts.
