Thermal diffusivity measurement using photoacoustic and thermal lens techniques
The open photoacoustic cell (OPC) technique was used for measuring thermal diffusivity of solid samples. It is based upon the measurement of the photoacoustic signal as a function of the modulation frequency in the region where the thermal diffusion length equals to the-sample thickness. The meas...
