ABSTRACT:
An interlayer material is scanned prior to laminating same with glass sheets to generate a thickness variation signal, a wedge angle signal and an optical power signal. The signals are then selectively filtered to determine the thickness variation, wedge angle and optical power of the interlayer after lamination.
