Abstract
We present a new laser method that exploits curved-ray effects and that provides a practical method to investigate the stress profile in tempered glass. A feature of the technique is that the probing laser beam curves sufficiently that it exits on the same side as it enters; it does not reflect off or exit from the opposite side. The governing equations are formulated and studied using analytical methods and computer simulations. For a typical piece of tempered glass, the distance between the entry and exit points is of the order of a few tens of centimeters and is highly sensitive to details of the underlying stress distribution.
