Keywords:Laser induced vibration, Bolt looseness inspection

This research aims to measure the friction coefficient, which constitutes Motosh's equation, by applying laser resonance frequency analysis to a sample whose axial force and fastening torque have been evaluated in advance, and to understand the loosening inspection of bolt fasteners by laser remote sensing.
