Ξ传统光学显微镜与近场光学显微镜祝生祥(同济大学 Po h l 固体物理讨论所, 上海200092)摘要: 近场光学显微镜是对于常规光学显微镜的革命。 它不用光学透镜成像, 而用探针的针尖在样品表面上方扫描获得样品表面的信息。分析了传统光学 显微镜与近场光学显微镜成像原理的物理本质和两种显微镜系统结构的异同 点。介绍了光纤探针的制作方法。重点讨论了近场探测原理、光学隧道效应及非 辐射场的性质。关键词: 扫描近场光学显微镜, 光学显微镜, 近场探测原理, 悬臂式光纤探 针。O p t ica l m icro scopy an d n ea r- f ie ld op t ica l m icro scopyZ H U S h en g x ia n g(Po h l In st itu te o f So lid S ta te P h y sic s, T o ng ji U n ive r sity, Sh angh a i A bstra c t: N ea r2f ie ld op t ica l m ic ro scop y is a revo lu t io n in th e dom a in o f th e op t ica lm ic ro scop y.
