Abstract
Many applications require micro-vibration measurement, especially multi-points detection at long distance in real-time. In this paper, a micro-vibration measurement approach based on digital holographic interferometry is proposed for middle-low frequency detection. It can be used to monitor irregular frequency/amplitude vibration in selected region over 10m away simultaneously and synchronously. A series of experiments were conducted including real-time measurement of 300Hz, 1kHz, 2kHz and 3kHz constant frequency/amplitude periodic vibration, precision and frequency response tests with calibration of LDV, 1kHz irregular amplitude vibration, irregular frequency/amplitude vibration as well as the real-time measurement and simultaneous display of multi-points vibration. The experimental results demonstrate the feasibility of the proposed method and reveal its unique advantages.
