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.
Claims31
A detection system for measuring glass that has been placed under strain and any resulting stress lines in the glass, comprising:
- at least one light source configured to create a non-continuous light distribution;
- the light distribution being configured to have a discontinuity which enhances the viewing of a photoelastic effect in the glass, wherein the light source is configured to create a viewable optical interference resulting from stress lines in the glass.
A method for measuring stain or stress lines in glass, comprising:
- providing a light source, creating a discontinuous distribution of light from the light source, generating a viewable optical interference which results from any stress lines present in the glass, and detecting any strain present in the glass.
