As material changes during the production or reaction processes, its thermal properties are expected to change with time. However, it is seldom conducted to take into account the properties variation for thermal design. We have developed the forced Rayleigh scattering method (FRSM) to apply the highspeed and real-time measurement of the thermal diffusivity of changing material. In the present study, theoretical considerations of measurement repetition interval and error analysis of property evaluation during one measurement are conducted. Continual measurement of sol-gel transition process of biopolymer has been carried out, and dynamical change of thermal diffusivity at the gelation point has been detected. The results illustrate the validity of FRSM to real-time thermal diffusivity monitoring technique of rapid process.
