Abstract
A system for monitoring and controlling the width of a product such as a sheet, film or tube includes, in the preferred embodiment, a line scan camera having a one-dimensional array of charge-coupled devices ('CCD's') for monitoring the width of the product. The CCD's develop an analog charge value which is proportional to the intensity of any light falling thereon; the analog nature of the CCD's allows subelement interpolation based on the voltage charge of two adjacent elements. This permits product width to be measured more accurately than was heretofore possible with electromechanical or photoelectric type systems.
