| Abstract: | A new direction seeking circuit for subdivision of the fringes of a digital interferometric fiber optic sensor is proposed.Because of larger number of sub-division,the digital fiber optic interferometer requires higher resolution of direction seeking circuit while the basic direction seeking circuit can't meet the requirement.Simulation proves that the new circuit can meet the requirement.The circuit also can be applied to traditional sub-division technique of Moire fringe. |

| Keywords: | digital fiber optic interferometer sub-division direction seeking. |
