[15a-PA1-2] Polished surface vibration displacement measurement of piezoelectric device with Laser speckle interferometer.
Keywords:laser speckle, interference, correlation coefficient
It succeeded in obtaining a linear profile in the measured thing using the correlation coefficient in the laser speckle interference. It experimented on targeted a polished surface piezoelectric device, and reported the research progressing for the laser speckle interferometer.
