Abstract: The present invention relates to an apparatus and method for measuring thermal diffusivity using the flash method. The apparatus includes: a laser generator 60 for generating a flash beam 30; a measurement sample 10 having graphite layers 20 formed on front and rear surfaces thereof, through which the flash beam 30 passes; an infrared sensor 70 disposed at the rear of the measurement sample 10 for measuring a temperature and time at the rear surface of the measurement sample 10 from heat 40 dissipated from the measurement sample 10; and operation means 80 for performing an operation based on an output signal of the infrared sensor 70.

Abstract: The present invention relates to an apparatus and method for measuring specific heat using flash. To this end, the specific heat measurement apparatus includes sample fixing means for fixing a sample 50 so that each of both surfaces 52, 55 of the sample 50 is partially exposed, flash irradiation means for irradiating flash to one surface 52 of the sample 50, which is exposed by the sample fixing means, a light-receiving detector for receiving light irradiated from the other surface 55 of the sample 50, which is exposed by the sample fixing means, and a calculation unit 74 for calculating specific heat of the sample 50 based on an output signal of the light-receiving detector.
