発明の名称 (英語) STRESS VISUALIZATION DEVICE, AND MECHANICAL PROPERTY VALUE VISUALIZATION DEVICE 新技術説明会
発明の概要(英語) A control computation unit 114 changes the state of polarization by using an optical modulator 110, thereby shifting the phase of polarized waves illuminating an object W to be measured, and on the basis of phase differences among interference signals obtained during each phase shift of the of polarized waves, computes a spatial gradient of a phase difference stratigraphic distribution of the interference signals, and produces a visualized display on a display device 116, in which the stratigraphic distribution of the spatial gradient is associated with a stratigraphic distribution of stress. On the basis of the light interference signals, the control computation unit 114 computes a deformation rate vector distribution at a stratigraphic position of the object to be measured, and further computes a strain rate tensor stratigraphic distribution. A mechanical property value stratigraphic distribution is then computed on the basis of the stress stratigraphic distribution and the strain rate tensor stratigraphic distribution, and a visualized display is produced.
