Abstract

A novel combination of image formation theory, along with optimal digital estimation theory was employed in development of a new optical probe suitable for a variety of high speed sensing applications, such as in-process manufactured part inspection. Experimental results demonstrate a robust, 40,000:1 range-to-resolution ratio. The sensing strategy also utilizes multiple, simultaneous illumination beams such that it is possible to accurately estimate surface orientation for robotic guidance applications. A significant element in this research was the development of a technique which is least influenced by surface finish roughness as commonly found on manufactured surfaces. Experimental results are provided to demonstrate the validity of the theoretical models.
