Abstract
A method of measuring width of an object between two of its edges is disclosed wherein the object is placed between the edges of an aperture and a narrow beam of parallel light is directed through a rotating prism so as to scan the aperture and object therein, the light passing through the aperture being detected, and electrical signals generated proportional to the time the object interrupts the light are summed with correction signals generated in synchronization with the sweep of light across the aperture which are representative of the variation in sweep velocity to provide a composite signal representative of width of the object independent of its position in the aperture.
