Abstract

To detect the crack of steel material surface

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 steel material. The system is effective in indicating crack depth.So it has certain applied value.
