Real-time Micro-vibration Measurement Using Synchronous Phase Detection
A sinusoidal phase modulating laser diode interferometer is proposed. It is used to measure micro vibration of an object in real time. The real time phase detector is constructed with a simple circuits. The amplitude and frequency of the vibrations are measured by synchronously detecting the phases in interference signal. The theoretical analysis and experimental results are given.
