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.
