213 スペックル干渉法とシェアログラフィ法併用による三次元表面変位・ひずみ計測システムの構築(OS6-3 光学的手法II)(OS6 実験力学の新展開)  [in Japanese] 213 Construction of Measuring System 3-D Surface Displacement ・ Strain by Speckle interferometry and Shearography  [in Japanese]

Speackle interferometry is a wholefield non-contact metrology technique for measuring displacementt, otherwise shearography is one for strain measurement. In order to combine both techniques, we proposed a new system utilized two Michelson interferometers. Phase shifting technique is also used to obtain wholefield information. In this study, the author measures out-of-plane displacement and strain of point loaded aluminium disk and in-plane displacement and strain of tensioned bar with hole is also measured.
