摘要
This paper reviews shearography and its applications in experimental mechanics and nondestructive testing. Shearography is an interferometric method for measuring surface displacement derivatives. Unlike holography, it does not require special vibration isolation; hence it can be employed in field/factory environments. The technique has already received wide industrial acceptance for nondestructive testing. Other applications include strain measurement, material characterization, residual stress evaluation, vibration studies and 3D shape measurement.
