We present the results of the analysis and experimental study of defect detection using whole field laser Doppler vibrometry (WFLDV). The nondestructive inspection (NDI) procedure is based on the vibrational mode evaluation for a test object with specified defect parameters. To evaluate the procedure, a clamped aluminum drum with radius R was selected as the test object. The introduced defect was a thickness loss of 2.5, 5.0, and 7.5% at the central part of the drum. The data from computational examination, based on finite element analysis, are compared with experimental data received from tests with LDV. Additionally, we present data from interrogation of a multilayer (carbon composite) element with present defects in a specific layer and examples of corrosion detection. The experiments show that the technique enables reliable defect detection, location, and quantification.
