| Abstract: | An asymmetrical heterodyne laser pro bo system used for detection of microvibra-tion is described. The experimental results show that a high sensitivity of about 1X 10-4nm/ Hz has been obtained. By this system, the microvibrations of thin film circuits driven by alternative voltages and the radiated aooustie field distributions of SAW focusing transducers were detected with satisfactory results. |
