介绍1996年申请的一项发明专利——光纤尖“共振原子力/光子扫描隧道显微镜（AF/PSTM）”图像分解方法。该方法用入射角以光纤尖轴线为π对称的光束照明样品消假像，在AF/PSTM双功能弯光纤尖共振频率条件下，采用等尖至样品平均间距（即等振幅）扫描或等光子隧道信息平均强度扫描两种模式成像，分解样品光学图像和形貌图像。用最简单的PSTM两介质模型推导了近似的图像分解的解析表达式，最后用PSTM四介质模型数值模拟结果说明了该方法是可行的和有效的。

An invented patent about the method for separating image of Atom Force/Photon Scanning Tunneling Microscope (AF/PSTM) and its numerical simulation results are introduced. In AF/PSTM π-symmetry lighting beams were used for eliminating false image. The AF/PSTM bi-functional tip is made of bent optical fiber and works on constant amplitude resonance. △I_CD and △I_CI are AC information of photon tunnel of AF/PSTM under constant average distance (〓→A )scanning mode (constant amplitude mode) and constant average intensity scanning mode respectively. Both (△I_CD/〓_CD)² and (△I_CI)² are approximately linear with refractive index (n₁) of the sample. Results of the numerical simulation illustrate that the method for separating image of AF/PSTM is efficient. AF/PSTM constant average distance (〓→A ) scanning mode (constant amplitude mode) has more advantages than that of constant average intensity one, such as the better response sensitivity of refractive index of the sample, and ability of getting three images of transmisitivity, refractive index and morphology of sample simultaneously. Some excellencies of this method are listed at last.
