  • Method and apparatus for measuring ripple and distortion in a transparent material
    Patent number: 6909502
    Abstract: An apparatus and method for quantitatively measuring ripple and distortion levels in a transparent sheet (or film) material is provided. The apparatus includes a light source for projecting light beams onto a screen. A frame assembly is positioned intermediate to the light source and is adapted to hold the transparent sheet material at a predetermined angle and distance from the screen. The light beams pass though the transparent sheet material and projects an image onto the screen. The process includes digitally capturing the image and generating parameter signals from the digital image. The parameter signals are used in a model to quantitatively assign a value to the level of ripple and distortion present in the transparent sheet material.
