Abstract
In this paper, a simple measuring system is constructed to estimate the quasi-steady state temperature distribution in the work under CW CO_2 laser irradiation. This system is composed of an infrared camera, a video recorder, an image processor and a personal computer. The surface temperature of the work is measured by an IR camera, and computation based on a semi-analytical solution derived using Green's function is carried out by a personal computer. This system is applied to an actual laser materials processing experimentally to confirm efficiency of this system.
