Abstract
Apparatus for measuring the relief profile of a score line mode in a subste such as a paper board. A hand-held measuring head containing a light source illuminates the score line and the back-scattered light reflected therefrom is recorded by a CCD imager. The digital output of the imager is sent to a processor to determine one or more physical characteristics of the score line.
