Abstract

This paper describes a feasibility study done to demonstrate `ultra-high' resolution imaging with a triangulation-based 3D laser scanner. General requirements for micron-level 3D inspection applications are discussed, followed by a proposal of a laser triangulation-based system to address these requirements. Some fundamental limits and trade-offs of 3D imaging are reviewed, and methods for overcoming technical challenges are discussed. Finally, images from a prototype scanning system demonstrating sub-micron resolution at rates faster than 1 Mhz are presented.
