Abstract
The use of a laser scanning photothermal imager for the measurement of thermal effusivity of liquids is described. The method uses a single low frequency for excitation, which abridges instrumental requirements for irradiation and signal processing. The technique employs a simple liquid chamber that can accommodate liquids of high chemical activity too and is based on photothermal radiometry. A condition for linear response has been attained, based on which a liquid effusivity meter has been demonstrated.
