In-Plane Movement Measurement Technique Using Digital Sampling Moiré Method

Validating the efficacy of deformation distribution measurement in CFRP laminates during three-point bending using the sampling moiré method

“…However, the Sampling Moiré method introduced in our study shows unique strengths in dealing with complex materials such as CFRP. Compared to traditional methods, the sampling moiré method is notable for its ability to accurately measure displacement and strain distributions [1,[9][10][11][12][13][14]15]. Additionally, this method shows a significantly better resistance to noise, which further bolsters its reliability and effectiveness in capturing fine details in deformation analysis.…”

Vision-Based Vibration Monitoring of Structures and Infrastructures: An Overview of Recent Applications

“…However, non-contact monitoring technologies probably attracted most of the recent interest of the engineering community, e.g., [36]. Various approaches were explored in civil engineering for vibration testing; that is, laser Doppler vibrometry, e.g., [37][38][39][40]; microwave radar interferometry, e.g., [41][42][43][44][45]; infrasound, e.g., [46,47]; global positioning system (GPS) sensing, e.g., [48][49][50][51]; satellite remote sensing, e.g., [52][53][54][55][56][57]; theodolites and total stations, e.g., [58,59]; optical methods based on the moiré effect, e.g., [60][61][62][63][64]; and optical visionbased methods using digital image correlation (DIC), e.g., [65][66][67][68][69][70][71][72][73]. Indeed, the possibility to eliminate physical installations of sensors is very attractive, especially for structures that might not be easily or safely accessible, yet requiring rapid assessment of their conditions, for example, following extreme events such as strong earthquakes, explosions, or floods.…”
