PROCESS AND DEVICE FOR THE INSPECTION OF GLASS

A process and a device for inspecting glass including the use of a laser to illuminate successive cross section planes YX of a piece of glass to be inspected by relative displacement of a light curtain formed by the illumination source. A camera detects a reflective radiation emerging from the piece of glass in an observation direction which is oblique to the plane YZ of the light curtain in order to form images on the camera which include two lines corresponding to the upper and lower faces of the piece of glass and any possible luminous points situated between these two lines which would correspond to inclusions within the thickness of the glass.
