Abstract
Apparatuses and methods are described for detecting inclusions in glass. The apparatuses and methods employ a laser that is configured to project a laser sheet at a first angle from one side of a glass sheet, and a camera configured to capture images from a second angle from another side of the glass sheet. The glass sheet is moved thorough the laser sheet while the camera captures images. One or more processing devices execute image processing algorithms to identify areas of the glass sheet containing inclusions based on the captured images. In some examples, the identified areas of the glass sheet are revisited to confirm they contain inclusions.
