提出了一种基于光热振动的吸力显微镜。利用强度调制频率为共振频率的激光束的光吸收作用对悬臂梁进行振动，并采用光学偏转法对其进行检测。用镍箔悬臂梁测量了样品的光热振动特性和吸力梯度随针尖-样品距离的变化。记录了由聚碳酸酯和镁铝合金制成的数字存储盘的形貌图像。
An attractive force microscope using photothermal vibration is presented. A cantilever is vibrated by the optical absorption of a laser beam whose intensity modulation frequency is at resonance frequency, and the vibration is detected by an optical deflection method. The characteristics of the photothermal vibration and the attractive force gradient versus tip‐sample distance have been measured with a Ni foil cantilever. Topographic images of digital memory disks made from a polycarbonate and Mg–Al alloy were recorded.
