Paper Abstract

This paper describes a machine vision based technique to measure the profile of small aspheric convex optics. The proposed technique uses a video camera to view the horizontal profile of convex optics. A vision processor captures the image and calculates the best-fitted surface profile expression and related parameters based on a priori knowledge of the lens. This technique offers an efficient and easy way to measure small aspheric optics in manufacturing environment.
