Paper Abstract

This paper describes the concept of differential inspection using a digital 3D imaging laser camera. Shapes can be compared and analyzed to a resolution smaller than 25 micrometers . Differential information is displayed as a high-definition image, color-coded for human interpretation. The same concept of differential inspection can be applied to 3D color images in order to monitor shape and color variations. Potential applications are discussed.
