The invention relates to a method and a system for detecting internal defects of light absorption glass. The detection method comprises the following steps: 1) heating a light absorption glass test piece; calculating the theoretical heat conductivity coefficient of the light absorption glass according to the glass components; 2) detecting temperature distribution on the surface of the test piece; determining a temperature abrupt change area and a volume size thereof according to the temperature distribution; 3) continuously measuring real-time temperature values of the test piece at different rod length positions; calculating the actual heat conductivity coefficient of the light absorption glass according to the heat radiation energy and the thickness and sectional area of the test piece; 4) determining the type of the internal defect according to the temperature distribution on the surface of the test piece; and determining the material type of the internal defect according to the volume size of the temperat
