扫描近场光学显微镜（ＳＮＯＭ）提供了次波长的空间分辨率．通常将它用于高分辨形貌研究．近来出现了一些报道，将它与各种光谱方法联合使用，开展了近场光谱研究．已经成功的在次波长的空间进行飞秒超快动力学，发光光谱和拉曼光谱等研究．这种近场光谱技术为纳米结构和生物
Scanning near-field optical microscopy (SNOM) provides sub-wavelength spatial resolution. It is often used for high-resolution morphology studies. Recently there have been some reports that have been used in conjunction with various spectroscopic methods to develop near-field spectroscopy. It has been successful in the subwavelength space femtosecond kinetics, luminescence and Raman spectroscopy studies. This near field spectroscopy is nanostructures and biology
