Spatially resolved and spectroscopic imaging for regions around a near-field optical excitation site

近场成像技术的应用大大提高了光学显微镜的空间分辨率。然而，通常的近场显微镜从近场光激发点周围的区域以及该点本身检测光学响应。本研究提出了一种近场光激发点周围区域空间分辨光谱成像的实验方法。这种方法使我们能够研究光激发点的光响应流，这将为光电子学提供有用的信息。

Spatial resolution of optical microscope has been greatly improved by the use of near-field. However, usual near-field microscopes detect optical responses from regions around a near-field optical excitation site as well as the site itself. In this study, an experimental method of spatially resolved and spectroscopic imaging for regions around a near-field optical excitation site. This method enables us to investigate flow of optical responses from the optical excitation sites, which will provide useful information toward optoelectronics.
