Abstract
This system brings forward the CCD measurement method based on oblique laser triangulation , which to resolve the minimal thickness measurement precision problem, in this system use linear array CCD, then used CCD as a photoelectric conversion device, the image on the CCD image point displacement variation to realize planar sheet thickness measurement, design and construction of the contactless thickness measurement system. Finally, the experimental analyze the measurement error of the system, prove the feasibility and validity of the system.
