Improved depth characterization of internal defect using the fusion of shearography and speckle interferometry
Gu, Guoqing; Pan, Yun; Qiu, Chengchun; Zhu, Chengjie (Optics and Laser Technology, 2021)A hybrid nondestructive testing (NDT) approach based on the fusion of shearography and digital speckle pattern interferometry (DSPI) is proposed for depth characterization of internal defect. To this end, a novel dual-sensitive ... -
Real-time dual-channel speckle interferometry based on an improved dual-observation configuration with spatial phase-shifting
Gu, Guoqing; Pan, Yun; Qiu, Chengchun; Zhu, Chengjie (Measurement, 2021)This paper develops a real-time dual-channel speckle interferometry system based on an improved dual-observation configuration to address the issue of simultaneous measurement of the out-of-plane displacement and slope. A ...
