The Imaging Realization of Non-Probe Near-Field Optical Microscope

摘要: 介绍一种非探针近场光学显微镜，并对它的图像实现过程及处理方法进行了讨论。该装置以阿达玛变换成像理论为基础，用纳米多孔编码板代替光纤探针获得了较高的光学信噪比。成像研究表明，该装置可对近场衰逝波分量进行有效探测并能实现超衍射极限成像，为近场光学探测研究提供了一种新的思路。

Abstract: The nonprobe nearfield optical microscope is introduced in this paper, and the processing method and realization of the images are discussed. Based on the theory of Hadamard Transform imaging, the nonprobe nearfield optical microscope, which replaces the fiber probe with the nanometer multiaperture encoding mask, has a high optical signaltonoise ratio. The research shows that the nonprobe nearfield optical microscope can detect the evanescent nearfield wave effectively and the image with a superdiffraction limiting resolution can be obtained.All this will provide a new method for the research of the nearfield optics.
