| Research Abstract |
The piezoelectric device is used in much electronic equipment including an information and communication apparatus. FEM (finite element method) is usually used for the design, and it becomes the convincing means to measure the vibration mode of the piezoelectric device produced experimentally in design inspection experimentally. By experimental inspection, I can get the information about the spurious mode which is not provided from an analysis result.
In this laboratory, you suggest the laser speckle method visualizing a vibration mode at high speed using interference light (speckle) and an image processing technology of the air-light to produce when you irradiated the coherent light such as the laser beam to piezoelectric device appearance handled coarsely. In addition, the measurement of the vibration distribution is possible very in a short time because I do not need mechanical scanning.
