Paper Abstract

In this paper, a new method of optical scanning measurement was put forward, using the semiconductor laser and octagon prism. This method realized on-line non-touch measurement of the necking value and necking position in the process of material tensile testing by the assist of machine scanning. The principle and key technical of this measuring method had been introduced, and the main factor to the measurement accuracy was analysed too. It is shown by test that this method is more accurate, faster and simpler than ever before for giving out the capability of material by omnipotence tensile machine.
