Abstract

Compared with traditional electrical accelerometers, the fiber optic interferometric accelerometers have the unique advantages such as high precision and anti-electromagnetic interference to be widely used. Sensitivity is an important parameter of the fiber optic interferometer accelerometers and this paper mainly studied the influence factor of sensitivity. Meanwhile, this paper focuses on analyzing the winding fiber optic length and the structure of interferometric accelerometers for the influence of sensitivity. At the same time, this paper experimented and verified the theoretical derivation calculation of factor influence of sensitivity. This paper lays the theoretical foundation for the design of specific sensitivity of fiber optic interferometric accelerometers.
