Abstract:Surface roughness presents microsurface topographic variances and irregularities; it is an important characteristic in many experiments and model construction. A quick testing method and an instrument for surface roughness measurement were developed in this study. A laser was emitted onto the test subject, the reflected light was directed to the camera and the images were then captured through a linear scanning process. The three-dimensional (3D) coordinates of the measurement area were then obtained after ima… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
