A novel scheme of a fringe count interferometric accelerometer is proposed. In view of practicability, the sensor must be made up of only fiber. Two 3dB directional couplers and singlemode fibers are used in this scheme to compose an imbalance Mach-Zehnder interferometer. Phase modulation is achieved by modulating LD frequency to scan the interference fringes. With special technique, only one PIN is needed to count and identify the moving direction of the interference fringes. The signal can be transmitted more than several kilometers in a pair of fibers. The two arms of the interferometer work at push-pull mode, which is favorable for temperature compensation. The resolution is significantly improved by fringe sub-division. A real-time dynamic vibration signal can be measured without distortion by this system.
