Abstract

To achieve non-contact non-destructive detection of corrosion in metal artifacts, this paper presents a novel metal corrosion detection system employing a pulsed modulation laser source, MEMS scanning micro-mirror, optical lens assembly, photoelectric detector, and FPGA. The detection system's measurement theoretical model is established, and corrosion measurements are conducted on corroded metal samples using the developed system. The research reveals that corrosion products adhering to the surface of metal samples reduce the reflectance of light, leading to a decrease in the light flux reaching the photoelectric detector and a subsequent reduction in the output voltage of the detection system. The corrosion intensity of metal artifacts can be detected by acquiring the output voltage of the detection system. Simultaneously, the corrosion behavior characteristics of metallic specimens can be identified based on the scanning voltage of the detection system.
