Abstract
A nondestructive multispectral vibrothermography inspection system includes a fixture to retain a component, an ultrasonic excitation source directed toward the component retained within the fixture, a laser Doppler vibrometer directed toward the component retained within the fixture, and a multispectral thermography system directed toward the component retained within the fixture. A method for nondestructive multispectral vibrothermography inspection of a component, includes generating ultrasonic excitations in a component over a broad range of frequencies; determining a spectral signature in the component from the excitations; comparing the spectral energy signature against databaseof correlations between vibrational frequencies of a multiple of components and the spectral energy distribution thereof, and classifying the component based on the database data.
