Studies on Digital Shearography for Testing of Aircraft Composite Structures and Honeycomb-based Specimen

摘要：

This paper reviews shearography and its applications for testing of aircraft composite structures and honeycomb-based specimen. Shearography is a laser-based interferometry in conjunction with the digital imaging processing technique for full-field measurement of surface deformation. It reveals defects in an object by looking for defect-induced deformation anomalies. It does not require special vibration isolation, and with the development of a small and mobile measuring device(portable inspection system), it can be employed easily in field/factory environments.
