APPLIANCE FOR DETERMINING THE VARIABLE THICKNESS OF A COVER ARRANGED ON A SUBSTRATE AND METHOD FOR DETERMINING THE COATING THICKNESS AT VARIOUS SURFACE POINTS

摘要

APPARATUS FOR DETERMINING THE VARIABLE THICKNESS OF A COATING ARRANGED ON A SUBSTRATE AND METHOD FOR DETERMINING THE COATING THICKNESS OF VARIOUS POINTS OVER THE SURFACE OF A SUBSTRATE. It is an apparatus for determining a varying thickness of a coating on a surface of a substrate using, in part, a flash lamp source capable of generating a thermal pulse on the coating surface, and a device for image capture and processing capable of capturing sequential image frames of the coating surface, whereas each sequential image frame corresponds to an elapsed time, and comprises a pixel matrix, and each pixel of the matrix corresponding to a location in the coating surface. A method of calculating the coating thickness is also provided.
