摘要：

In this paper, the characteristic of thermal induced non-reciprocal phase noise was analyzed theoretically, and the temperature distribution model was derived for the fiber sensing coil. The zero point drift of the fiber optic gyros(FOG) induced by outside temperature fluctuation was simulated numerically and compared for the four type fiber sensing coil manufacture methods (ZYL, SYM, DIP, QUA). The related zero point drift compensated method was proposed.
