Abstract
A particle detection system includes a light source configured to emit a light beam into a cylindrical glass article when the cylindrical glass article is imaged by the glass particle detection system. The light beam is directed along a beam propagation axis that is perpendicular to a longitudinal axis of the cylindrical glass article. The particle detection system further includes a first polarizer positioned between the light source and the cylindrical glass, a camera configured to capture an image of the light beam reflected from the cylindrical glass article, and an analyzer positioned between the cylindrical glass article and the camera. An optical axis of the camera is perpendicular to the beam propagation axis of the light source.
