Quick Summary

Stress-analysis holography is a scientific technique used for visually observing strain on an object. It involves superimposing a hologram of an object over the object itself. When the object and its hologram align perfectly, nothing unusual is seen. However, if the object is subjected to stress, fringe patterns emerge, allowing for the determination of the strain on the object. This method is a form of holography, which is a technique for creating three-dimensional images without a lens by recording and reconstructing light waves' intensity and phase. Holography has applications in nondestructive testing, such as detecting flaws in materials like tires.123

…an object are photoelasticity and stress-analysis holography. Photoelasticity provides a visual method of observing the strain on an object by viewing the effects of polarized light on a bi-refringent (double-refracting) material bonded to the object. As the test object is stressed, fringe patterns in the bi-refringent material represent the regions…
