Abstract

Laser-induced capillary wave (LiCW) using pulsed infrared heating laser is a non-contact and optical viscosity measurement technique to measure food and biological liquid sample viscosity with only a microliter-order sample volume and measurement time of the millisecond-order. In the previous study, to develop a practical viscosity sensing apparatus with LiCW, we proposed the method with volume heating[1]. This paper focuses the effect on the temperature dependence of surface tension, we theoretically calculated the uncertainties of surface heating and volume heating in the case of toluene on the viscosity and surface tension measurement. In addition, in order to verify the advantage of volume heating compared with surface heating, we experimentally demonstrated the measurement of decanol aqueous solution which shows the minimum value of surface tension at room temperature.
