Abstract
A method and apparatus for inspection of the optical quality of a glazing is provided. A greyscale image is generated digitally, and reflected off or transmitted through a glazing, and captured using an image capture device. Preferably, the generation of the greyscale pattern and the capturing of the reflected or transmitted greyscale pattern are synchronised.
