The Quantitative Indication System to Crack Depth on the Surface of Metal Material

摘要：

The aim of this paper is to detect the crack depth of metal material surfaces. As a methode we use: a phase sensitive circuit is used to detect the signal of cracks and restrain interferential signal. The correlative circuit modules are used to design the quantitative indication system for crack depth on the surface of metal material. We conclude that the system is effective in indicating crack depth.
