Abstract:We present an experimental approach to rapidly measure the 3D shape of a micro deep drawing part, which is based on a digital holographic contouring. Inline quality control in a micro deep drawing process requires a rapid and nondestructive measurement technique, which is the significant advantage of digital holography. The surface structure of the investigated object is dominated by the properties of the drawing process. Therefore, we investigate the statistical properties of the light scattered from the surf… 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.
