摘要： 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.

摘要： A system for the inspection of and a process for the correction of defects in a microreplicated optical display film manufacturing process. The process steps of manufacturing a master, a plurality of shims from the master, and a multiplicity of display films from each shim are integrated with a systemic defect identification and correction process. Each primary manufacturing step has its own inspection system and correction process where defect information for that step of the process is fed back and analyzed; and from that analysis the subprocess is adjusted to eliminate or reduce the detected defect. The systemic defect is identified as to its source and then fed back and analyzed in the correction step of the respective subprocess in order to cure the root of the defect.
