We introduce a loss compensation method to increase the resolution of near-field imaging with a plasmonic superlens that relies on the convolution of a high spatial frequency passband function with the object. Implementation with incoherent light removes the need for phase information. The method is described theoretically and numerical imaging results with artificial noise are presented, which display enhanced resolution of a few tens of nanometers, or around 1/15th of the free space wavelength. A physical implementation of the method is designed and simulated to provide a proof-of-principle, and steps toward experimental implementation are discussed.

非相干主动卷积照明增强的等离子超透镜成像

我们引入了一种损耗补偿方法，以利用依赖于高空间频率通带函数与物体的卷积的等离子超透镜来提高近场成像的分辨率。用非相干光实现无需相位信息。从理论上描述了该方法，并给出了带有人工噪声的数值成像结果，这些结果显示出几十纳米的增强分辨率，或大约是自由空间波长的1/15。设计并模拟了该方法的物理实现，以提供原理证明，并讨论了实现实验的步骤。
