A system is described for viewing the end face of product 62. The system comprises means for illuminating the end face, and a video camera 78 for producing a video signal from an image of the illuminated end face. The end face is illuminated by light of two predominantly different wavelengths. One wavelength illuminates an area which contains both the end face and surrounding parts of the machine, while the other wavelength from a laser source produces a pattern of parallel spaced apart lines of light 64. The vision system forms part of a product slicing machine and measurements and/or dimensional values obtained from the video signal control the thickness of the next slice to be cut and are also sent to slice and pack grade-level decision logic, to control down-line gates. |
