Abstract: In order to investigate the temperature distribution of the soda-lime glass irradiated by laser beam,experimental and numerical computing method was used.The temperature distribution of the soda-lime glass on the surface of the heated region under CO2 laser irradiation was measured with the thermovision infrared system.The thermocouple device was used to correct the thermovision infrared system,so the real temperature distribution was obtained.The result showed that the experimental temperature transformation was in accordance with the numerical computing.
