An ultrasonic omni-directional sensor device for coverage structural deformation monitoring

Abstract: Underground space has to be monitored for regional coverage deformations. This issue remains a challenge for current deformation monitoring techniques. In this study, a new high-coverage regional monitoring method is presented to address underground space deformation by using the divergent feature of an ultrasonic sensor. The working principle for coverage regional monitoring, which uses the divergence feature of an ultrasonic beam to increase the monitoring area coverage, is proposed. Space and mathematical m… Show more

“…NDT&E methods are required to be low-cost, fast detection, noncontact, anti-interference, and high-accuracy. There are now many well-established NDT&E solutions such as optical method [2,3], radiography [4,5], ultrasonic [6,7], penetrant testing [8], acoustic emission [9], magnetic flux leakage [10], metal magnetic memory [11], electromagnetic method [12], and pulse eddy current and thermography-based NDT [13,14].…”
