This article proposes a laser-induced surface displacement detection instrument for measuring the viscosity of liquid. The features of this instrument can obtain the absolute value of timeresolved surface displacement with an adjusted-free and non-calibration. The constitution method of our proposed apparatus and its trial prototype are shown, and experimental results are demonstrated. Finally, our proposed scheme that estimates liquid viscosity is described briefly.
