Course Overview
Laser Shearography is an optical, Non-Destructive Testing (NDT) surface measurement technique that works on the principle of laser-speckle shearing interferometry. Through the application of a load or excitation to an object‘s surface, a shearography sensor can observe surface bending in the form of an out-of-plane strain field. The measurement attained is imaged as a phase map presenting the relative difference in the two (reference/deformed) states as fringes. Local structural weaknesses caused by discontinuities are indicated by isolated fringes.
This presentation will introduce the fundamentals of Laser Shearography and discuss its advantages and limitations from an applications perspective.
Upon Completion, Learners Will Be Able To:
- Identify the basic components of a Laser Shearography sensor
- Explain laser interferometry
- Describe the basic working principle
- Distinguish the advantages of Laser Shearography as an NDT method
- Recognize the defect detectability limitations of the technique
