  • Publication number: 20060192177
    Abstract: An essentially thickness independent luminescent photoelastic coating is a single layer having a photoelastic material, a polarizing preserving luminescent dye, and an excitation absorption dye therein. The absorption dye limits a penetration depth of excitation radiation incident on the layer. The thickness of the layer is greater than a penetration depth of the excitation radiation. A strain measurement system and associated method of determining strain utilize the single layer coating.
