Abstract
We report on simple high-sensitivity interferometric technique of detecting vibrations of piezoceramic plates using adaptive photodetectors. It enables efficient direct conversion of high-frequency phase modulation of speckle-like optical wave reflected from vibrating plate into an output electrical signal with concomitant setting of optimal operation point of the interferometer and suppression of amplitude laser noise.
