Flash Diffusivity measures how well energy can be transferred through a sample. The
process for measuring thermal diffusivity of a material is done by hitting one side
of the sample material with a pulse of intense light and monitoring the other side
of the sample for temperature change. The trend of time and temperature is measured
and the several rise times are determined from the trend. The measured half rise time
can be input into a model to determine the thermal diffusivity of a material. Specific
heat can be determined by running a sample with known specific heat capacity and then
running the unknown sample.
