Outline of Final Research Achievements

In this study, a high-speed measurement method using multi-imaging sensors and reference planes for 3D shape, deformation and strain distribution measurement was developed. A high-speed trigger control unit and multi-camera unit were prototyped. A weighting phase analysis method (WPAM) to analyze 2D phase accurately was developed. A high-speed measurement system was developed with integration of these devices and software. As the evaluation, two experiments were performed. First, a rotated angle on a high-speed rotated plate was measured at intervals of 20 micro-seconds accurately using the developed system. Second, 3D shape and strain distribution of a bounding rubber ball was measured at intervals of 20 micro-seconds accurately.
