Title:
輪郭を有する構造体の検査用のレーザー超音波システム及び方法
Document Type and Number:
Japanese Patent JP6987488
Kind Code:
B2
Abstract:
A method including ultrasonically scanning a structure with a laser ultrasound testing system where the structure is provided with an array of nanoscopic structures, the nanoscopic structures having a predetermined directional orientation, the nanoscopic structures disposed on a scanned surface of the structure, and determining if the structure meets a predetermined threshold. Aspects of this invention apply certain high emissivity coatings to structures for the purpose of significant improvement laser ultrasound inspection of those structures. The nanotechnology-based material in the coatings rapidly draws heat away, for maximum laser energy absorption while preventing surface heat damage to the composite surface from the laser beam.
