  • Method and apparatus for automated in-line inspection of optically transparent materials
    Patent number: 11415528
    Abstract: A method and system for automated in-line inspection of optically transparent material is disclosed herein. The method includes illuminating a top and bottom surface of the optically transparent material with at least one sheet of light and then generating an image based on light that is received by an imaging device. The image that is generated may either be a bright field image or a dark field image.
    Type: Grant

  • Bright field and dark field channels, used for automotive glass inspection systems
    Patent number: 8242477
    Abstract: An inspection system for inspecting a sheet of glass comprises an illumination module, a collimating lens system, a telecentric imaging lens system and a Time Delay Integration line-scan camera. The illumination module has a low coherence light source emitting light. The collimating lens system has a focal point on the main axis thereof on which focal point its light source is located. The collimating lens system produces a collimated sheet of light from the emitted light. This collimated sheet of light passes through the sheet of glass. The telecentric imaging lens system concentrates the sheet of light passed through the sheet of glass on an image formation plane.

  • BRIGHT FIELD AND DARK FIELD CHANNELS, USED FOR AUTOMOTIVE GLASS INSPECTION SYSTEMS
    Publication number: 20100051834
    Abstract: An inspection system for inspecting a sheet of glass comprises an illumination module, a collimating lens system, a telecentric imaging lens system and a Time Delay Integration line-scan camera.

The collimating lens system produces a collimated sheet of light from the emitted light. This collimated sheet of light passes through the sheet of glass. The telecentric imaging lens system concentrates the sheet of light passed through the sheet of glass on an image formation plane. The Time Delay Integration line-scan camera is positioned in a general area of the image formation plane. The camera is equipped with an antiblooming device. In another embodiment, an inspection system for inspecting a sheet of glass comprises a camera and a peripheral RDF illumination module.
