Abstract

A digital electronic glaziometer instrument for measuring the thicknesses of a glass panel and its constituent sheets and gaps is proposed. There is currently no reliable method or instrument for determining the thickness of individual glass plates or the distance between plates of an installed glass panel. A new device is proposed which uses a linear array detector to detect the positions of light beams reflected from the top and bottom surfaces of glass sheets. A breadboard model was built and experimental testing on a multi-glazed panel shows favorable results. Factors affecting instrument accuracy are discussed.
