Basic Theory

Sputter Mo thin film on a sample and periodically heat the surface with heating laser. Heat propagates through the Mo thin film and reaches to the sample. A phase lag occurs to the temprature response. The phase lag varies with sample’s thermophysical characteristics. Since reflectance of Mo changes according to the temperature, by irradiating and datecting the amplitude variation of a probe laser beam which is coaxial to the heating laser, relative temperature variation of the surface could be measured. By using this method, thermal effusivity measurement in high spatial resolution become possible. Heat capacity per unit volume and thermal conductivity could be calculated by optional software.
