We report the experimental observation of systematically occurring phase singularities in coherent imaging of sub-Rayleigh distanced objects. A theory that relates the observation to the sub-Rayleigh distance is presented and compared with experimental measurements. As a consequence, the limit of resolution with coherent illumination is extended by a factor of 1.64x.
我们报告了在亚瑞利距离物体相干成像中系统出现相位奇点的实验观察。提出了一个将观察结果与亚瑞利距离相关联的理论,并与实验测量进行了比较。因此,相干照明的分辨率极限提高了 1.64 倍。
