Paper Abstract

The increasing use of automated manufacturing processes is directing attention to the urgent requirement for on-line product inspection and the potential application in industry for new forms of optical sensor. This review paper describes the advantages and disadvantages of optical sensors used for product inspection and indicates the hazards to be overcome by the systems designer. The design process is illustrated by reference to a selection of product inspection problems involving the use of laser beam scanning, thermal detection and image analysis, which have been solved recently by the use of optical sensing techniques.
