Abstract
A detection system for measuring glass that has been placed under strain and the resulting stress lines in the glass has a light source of individual elements configured to create a light distribution. The light distribution has a discontinuity which enhances the viewing of a photoelastic effect in the glass. The light source creates a viewable optical interference (i.e., color changes) which results from stress lines in the glass.
