 note = {We are developing a new remote inspection method “high-speed laser hammering method” for detecting the defect in the tunnel concrete by using high power lasers. In this study, a practical use of the laser hammering system on vehicle was demonstrated in the road tunnel that is being used, and we have succeeded in the detection of the inner defect of the concrete.},
