PROBLEM TO BE SOLVED: To simultaneously measure the spindle thermal diffusivity and spindle angle of a three-dimensional anisotropic material. ;SOLUTION: One heating point 0 is determined on the surface of a three- dimensional anisotropic heat conductive substance sample 6, and at least five temperature measuring points 1-5 are determined at parts excluding the heating point. The heating point 0 is instantaneously supplied with pulse-like heat using a laser 9, and the temperature of the temperature measuring points 1-5 is measured. The measured temperature of one measuring point is set as a reference temperature T1, and four other measured temperatures are assumed T2-T5 to obtain the temperature difference T12=T1-T2, T13=T1-T3, T14=T1-T4 and T15=T1-T5. Three spindle thermal diffusivity k1, k2, k3 and spindle angle ϕk of the three-dimensional anisotropic heat-conductive substance are simultaneously measured using the temperature difference, the quantity of heat of an instantaneous heat source, the light absorptance of the sample surface and the position relation of the measuring points.;COPYRIGHT: (C)2001,JPO
