SCANNING SYSTEM FOR MEASURING WEDGE ANGLE AND CURVATURE OF AUTOMOTIVE WINDSHIELDS
摘要：we describe a non‐contact measurement approach that uses a scanning beam of light to measure thicknesses of individual layers (glass and PVB) in an automotive windshield, as well as its shape (curvature). Wedge angle of the PVB layer is also measured for windshields with HUD (heads‐up display) region.
