227 モアレ干渉法とトワイマン・グリーン干渉法併用による三次元表面変形計測システムの構築(OS6-6 ハイブリッド計測)(OS6 実験力学の新展開)  [in Japanese] 227 Construction of Measuring System for 3-dimensitional Surface Deformation Using Moire and Twyman-Green Interferometry  [in Japanese]

In order to measure 3-D surface deformation in the same site and situation simultaneously, a new optical set-up is constructed by combining Moire interferometry and Twyman-Green interferometry. Phase shifting techniques is applied to obtain 4 fringe image data for estimating u, v and w displacement separately. Furthermore, the phase connecting method using minimum spanning technique is applied to obtained rapping image data. Further improvement of image processing is needed for estimating accurate 3-D deformation.
