The purpose of this study is to evaluate the damage level of concrete delamination or internal defects using a concrete surface vibration waveform of the laser hammering system (LHS). By referring the laboratory test data, it was succeeded to evaluate the damage level by the method of evaluating attenuation graphs using a normalized wave energy curve.
