Abstract

This paper discusses laser-induced photoacoustic investigations; it concerns a non-destructive technique for the determination of the thermal diffusivity of colon phantom tissue employing open photoacoustic cell configuration. The theoretical value of thermal diffusivity is determined to be 5.65×10-4 m2 s-1 and found to be comparable with other conventional thermal-diffusivity measurement techniques such as laser flash method. The results obtained provide the evidence that photoacoustic spectroscopy (PAS) in open photoacoustic cell (OPC) configuration can be used as a reliable and inexpensive method for determining the thermal properties of samples such as colon phantom tissue.
