Abstract
Laser interference frequency ratio counting method is widely used in absolute vibration standard devices. However, it can only measure amplitude, and cannot get vibration phase. This paper studies a method of measuring vibration phase by using the relationship between laser interference fringes and vibration displacement of vibrostand, and gives a mathematical model of vibration phase measurement by laser interference waveform demodulation. Based on the homodyne Michelson laser interferometer, this method uses a high-speed data collector to synchronously collect laser interference signals and sensor signals, and demodulates the vibration waveform on the virtual instrument software platform, realizing the real-time measurement of vibration amplitude and phase.
