英文摘要：

This paper proposes a contactless method for internal friction measurement. The micro-scale material internal friction measurement system uses alternating voltage to stimulate carbon fiber specimen, records the high frame rate images of the forced vibration process under the microscope. Finally, data analysis and parameters measuring are completed based on image processing. The experiment results show that the measurement system can effectively measure low frequency and high frequency internal friction. It has wide frequency measuring range and great expansibility.
