The Rayleigh resolution criterion sets the minimum separation for two-point objects to be distinguishable in a classical optical imaging system. We demonstrate that the sub-Rayleigh resolution can be achieved in a telecentric imaging system with the help of a partially coherent illumination whose spatial coherence has lattice-like distribution. We show that the orientation-selective sub-Rayleigh imaging can be realized by controlling the spatial distribution of the coherence lattice into different symmetries. We carry out a proof-of-principle experiment to demonstrate the orientation-selective sub-Rayleigh imaging for a 1951 USAF resolution target. Our results indicate a flexible orientation-selective high-resolution imaging with spatial coherence engineering of the partially coherent light.

具有空间相干晶格的定向选择性亚瑞利成像

瑞利分辨率标准将两点物体的最小间距设置为在经典光学成像系统中可区分。我们证明了亚瑞利分辨率可以在远心成像系统中借助部分相干照明实现，其空间相干性具有晶格状分布。我们表明，可以通过将相干晶格的空间分布控制为不同的对称性来实现方向选择性的亚瑞利成像。我们进行了原理验证实验，以演示 1951 USAF 分辨率目标的定向选择性亚瑞利成像。我们的结果表明具有部分相干光的空间相干工程的灵活方向选择性高分辨率成像。
