Abstract:
1. An apparatus for measuring stress in walls of a glass container, comprising: a light beam source that generates a light beam; light beam coupling apparatus for directing said light beam at the side wall of a glass container at an angle facilitating entry of said light beam into and through the side wall of the glass container, said light beam causing fluorescent light to be emitted within the side wall of the glass container in response to said light beam within the side wall of the glass container; fluorescent light coupling apparatus for coupling a portion of said fluorescent light emitted in response to said light beam within the side wall of the glass container outwardly from the side wall of the glass container; and fluorescent light processing and analysis apparatus that processes the fluorescent light exiting the side wall of the glass container and determines the stress in the side wall of the glass container from the processed fluorescent light exiting the side wall of the glass container.
