This paper describes a new method for measuring the thermal diffusivity of liquid samples through inverse photopyroelectric detection measurement. It is proven that thermal diffusivity values can be obtained with both amplitude signals and phase signals in a low frequency range. At around 3 Hz, these values are found to correspond to their theoretical values. We experimentally prove that the piezoelectric effect, which films are known to exhibit, is negligibly small compared with the photopyroelectric effect.
