Abstract: 本論文中,主要是研究如何建立一套近場光學顯微鏡系統 及其一些特
性分析。 我們將描述此系
統如何從設計、組裝,以至於系統 完成的整個過程,包括所用之回饋系
統及電腦軟體控制。 此外,我們利用在近場中作用力的特性配合一市
售的音 叉,設計了一套全由電子式鎖相迴路控制的回饋系統,進
行樣品表面掃描。 最後
,我們也將探討不同回饋方式的優缺點及其三 維掃描結果,並說明我們
所得的光學影像結果。而此套顯 微鏡系統未來將可廣泛地應用到許多
領域中,作為一相當 有力的工具。
In this thesis , we haved accomplished the construction of the
Scanning Near-field Optical Microscope ( SNOM ) and examined
its characteristics .We will describe the buildup process of the
SNOM system ,such as : system design and assembly , in
particular the feedback system and computer software . We
also designed a new feedback system based on electronic
phase-locked loop ( PLL ) technique with a commercial tuning
fork to scan the surface of sample .
Finally , we investigated the advantage/disadvantage of the
different types of feedback system for 3-D topographic image
.Expermental results are analyzed .
