Outline of Final Research Achievements

A technique for displacement distribution measurement by speckle interferometry which can be applied under the random vibration as environmental disturbances was developed. In this technique, optimum images for obtaining interference fringes ware extracted from a large number of speckle images captured at both initial and deformed states. A compact interferometer could be constructed on a tripod, because a middle-crass power laser could be used in this technique. Random phase stepping method was applied using multiple optimum images for each state. Bi-directional measurement was performed using polarizations of the laser beams for each sensitive direction. By these techniques, bi-directional displacement distribution and strain components could be obtained under the environmental disturbance. Therefore, it is expected that ESPI measurements are applied for various fields by the developed technique.
