Abstract

PURPOSE: To correctly detect the thickness of a running body in a non-contact manner from the relative positional relationship between two bright spots by irradiating the both sides of the running body such as a rubber plate with a fine optical flux of laser beam so that resultant two bright spots may be guided and focuses upon a light receiving plane.
