Abstract

A range evaluation system is presented which uses a unique method of fringe projection to establish the range of points upon the surface of an object, viewed along the optical axis using a high resolution sensor. A range profile is obtained and by computing over a matrix of points, which represent a segment of the surface under view, the topographical form of the object can be determined.
