摘要
In this paper, the principle of phase-shift interferometry is first briefly introduced. Then it is used as an illustration to measure small surface deformation, and the measurement accuracy of 0.02μis obtained. This demonstrates that the technology has great significance for strain analysis in experimental mechanics.
