ABSTRACT:
The present invention relates to an apparatus and method for measuring thermal diffusivity using the flash method. The apparatus includes: a laser generator60for generating a flash beam30; a measurement sample10having graphite layers20formed on front and rear surfaces thereof, through which the flash beam30passes; an infrared sensor70disposed at the rear of the measurement sample10for measuring a temperature and time at the rear surface of the measurement sample10from heat40dissipated from the measurement sample10; and operation means80for performing an operation based on an output signal of the infrared sensor70.
