Abstract
Aimed at the research actuality of displacement distribution measurement of each point at the measured object surface in condition of micro-motion, we developed a high-speed image sensor based on low-speed CCD in this paper, which can be used for vibration measurement. The operating principle of the sensor and the collecting principle of synchronization data are analyzed. The sensor combined with sinusoidal phase-modulating (SPM) interferometry was used in vibration distribution measurement. Thus each vibration displacement of the measured object surface was gotten. So the displacement distribution measurement of a low cost, high-speed and high precision was realized.
