Line Beam Shaper for Intra-Oral Scanning Device

Abstract

This paper describes an optical system as the line beam shaper for an intra-oral scanning device. The line beam shaper needs to provide desired beam quality, including bean length, uniformity, line width and depth of focus while maintaining compact form factor. More specifically, the proposed optical system was demonstrated to use only the on-the-shelf lens element to resolve all the optical performance issue, and to lead to a versatile solution for varied specification.
