A fractal-based approach for the determination of concrete surfaces using laser scanning techniques: a comparison of two different measuring systems

Objective Analysis of Lateral Elbow Exposure with the Extensor Digitorum Communis Split Compared with the Kocher Interval

“…A laser-and-camera surface scanning system was used to digitize the bones in order to quantify the exposed surface area 10 . Each bone was positioned within a calibration frame and was scanned at multiple angles with use of a high-intensity linear laser (see Appendix).…”

ANN modeling of pull-off adhesion of concrete layers

“…In this standard, 3D parameters are denoted with the capital letters S and V in order to distinguish them from 2D parameters (usually denoted with the letter R). So far only a few cases of the use of 3D parameters, such as arithmetical mean height Sa, root mean square height Sq and surface bearing index Sbi, in the description of the roughness of concrete surfaces have been reported [38][39][40][41]. However, there have been no documented cases of the application of 3D parameters to the assessment of the pull-off adhesion of concrete layers.…”

Use of laser interferometry for measuring concrete substrate roughness in patch repairs

“…Finally, over the last 5 years, a number of researchers [16][17][18][19][20] used both experimental and commercial 3D laser scanners based on triangulation method to assess the surface of either asphalt pavements or concrete substrates. They are based on a laser emitter which produces a beam of energy that hits a point on the surface of the object under investigation.…”
