Tip sample distance control system is the key part of scanning near field infrared microscopy.
针尖样品的距离控制系统是扫描近场红外显微镜的重要组成部分。
Based on ASTF the influence of such parameters as tip-sample distance, tip aperture diameter and the incident Angle of illuminating laser beam on PSTM image has been discussed.
进一步根据角谱传递函数计算了不同样品的光子扫描隧道显微镜理论图像，分析了探针与样品的间距、探针孔径大小、照明光入射角等对光子扫描隧道显微镜成像的影响。
