A study of the performance of a depolarized fiber optic gyroscope utilizing miniature single-mode fiber sensing coils is conducted. The study includes the analysis of incorporating long and short Lyot depolarizers coupled with sensing coils with diameters of 0.6 and 2.4 in. The roles of the length of the depolarizers and size of the sensing coils are quantitatively correlated, based on the known material parameters in the theoretical model and the experimental data. Minimum depolarizer requirements necessary to minimize the standard mean deviation of the random drift in miniature interferometric fiber optic gyroscopes are presented.
