摘要
A novel all-fiber velocity interferometer with high fringe contrast (NAFVISAR) is proposed and demonstrated. The configuration of the AFVISAR utilizes PBS to remove the unwanted non-interfering light beams from the moving target, which can approximately double the fringe visibility constant of the system compared with Levin's structure. With shaker vibration experiment, it is shown that the NAFVISAR achieved a fringe contrast of 0.91.
