A laser triangulation sensor for vibrational structural analysis and diagnostics

Abstract: The industrial progress has reached a level in which it is necessary to understand the behavior of mechanical components and to monitor their conditions without disassembling them. Nowadays, a suitable methodology is based on vibrational analysis usually performed through acceleration signals measured directly on the system to be tested. However, in the last years, the industrial scenario has deeply changed due to the need for time reduction, in particular, for the control operations at the end of the producti… Show more

“…1) using the laser triangulation principle described in [4,5]. Measurement setups using one LTS were already presented, e.g., a system for the real-time gauge measurement in a train [6] or a system for the contactless dynamic displacement measurement [7]. A measuring system for online quality control of car engine block has been presented in [8].…”

“…Some contact-free, laser-based measuring techniques exist. But position-based techniques, such as triangulation have resolution problems in the higher frequency range (Soave, D'Elia, & Mucchi, 2020). Acoustic measurements are an obvious choice, since quality issues reported by a customer are often associated to sound quality.…”

“…Laser triangulation systems, as non-contact measurement instruments with high accuracy, strong stability, and fast response, have been widely applied in various fields such as contour measurement reconstruction, 1 surface defect detection, 2 vibration structure analysis, 3 and diagnostics. In different measurement scenarios, users have varying demands for resolution and range in laser triangulation systems.…”
