Proper positioning of temperature sensors is required to minimize error in measurements of thermal diffusivity. Calculating the proper position of these sensors a priori, however, requires knowing the very thermophysical properties of the material one is testing. Presented here are calculations illustrating how IR video might be used to optimize a biaxial, pulsed thermal diffusivity measurement system. Results will be shown for representative elastomers.
