【Abstract】 A new laser diode interferometer for micro vibration measurement is proposed. The interferometer can measure micro vibrations of an object in real time. The interference signal is analyzed with signal processing circuits and the amplitude and frequency of vibrations are obtained. The theory analysis is described. The experimental results verify the usefulness of the interferometer.更多还原
