Apparatus for nondestructive and noncontact inspection of composite structures based on terahertz wave and the method for the same

摘要

The present invention relates to a terahertz wave based composite structure non-destructive non-contact inspection apparatus and method for more accurately and effectively detecting tomographic information of a composite structure using a multi-joint robot capable of 3D movement, which is A terahertz scanner that collects 3D shape information, irradiates a pulsed terahertz beam with a 3D composite structure, and detects a terahertz beam reflected from the composite structure; A multi-joint robot that mounts the terahertz scanner and moves the terahertz scanner in three dimensions based on an inspection path; And calculating the inspection path of the articulated robot based on the 3D shape information of the composite structure, and detecting and visualizing the film thickness and internal defects of the composite structure based on the terahertz beam detected through the terahertz scanner. It may include a control unit.
