| Abstract: | A new scheme to sub-divide directly the fringe of a digital interferometric fiber optic sensor is proposed,the principles and the methods to realize the scheme are investigated.The theoretical and experimental results show that the number of sub-division employing this scheme is remarkably increased compared with that of the Moire-grating scheme. |

| Keywords: | Digital fiber optic interferometer Fringe count Direct sub-division Phase modulation |
