Abstract

According to thermal conduction theories of anisotropic materials that are irradiated with continuously modulated laser, a photothermal measuring method about the thermal conductivity tensor and the orientation of the principal axis of the conductivity of arbitrarily opaquely anisotropic materials is given based on the theories of So(3) group rotation.
