Lineal illuminating system for automatic x-y graphic colorimetric and texture testing

Abstract

A lineal illuminating system based on an optical fiber array is studied. It can be applied to automatic industrial inspection systems, e.g., those used for chromatic classification of ceramic floor tiles. Improvement in the existing system’s performance is achieved by using a collimated beam, as shown by both photometric analysis and experimental results. This system has been implemented as part of a real-time controlling tool in a production line.
