Infrared Thermal Wave Non-Destructive detection for the internal structure of metal Buddha head

摘要

This paper depicts a testing technology of nondestructive infrared imaging for acquiring internal structure information of metal Buddha head. Methods applying active infrared thermal imaging nondestructive testing technology. Data which was collected by IR camera was processed, the typical time thermograph and the curve of logarithmic temperature-time can get information of relative thickness in metal Buddha face. Infrared thermal imaging technology can be detect the inside information of metal Buddha head. It is feasible to conserve heritage in infrared imaging method.
