Abstract: PURPOSE: An interference signal output variance stabilization device of a fiber optic gyro and a method thereof are provided to reduce time and cost which are required to implement the fiber optic gyro. CONSTITUTION: An interference signal output variance stabilization device (701) of a fiber optic gyro comprises a standard offset voltage unit (703), amplitude gain controllers (702,705,707), integrators (704,706), and a peak detector (708). The standard offset voltage unit generates standard offset voltage which is set up as a center value of an analog/digital (A/D) converter. The amplitude gain controller sets up an amplitude gain so that the maximum value of interference signal output, which is generated by applying a modulating signal to an optical phase modulator (103) of the interference signal output variance stabilization device, does not exceed the maximum admissible input voltage of the A/D converter. The integrator is set up with a time constant to compare the DC offset voltage of the interference signal output with the standard offset voltage. The peak detector controls the amplitude gain of the amplitude gain controller by detecting the maximum value of the interference signal output and by comparing the maximum value of the interference signal output with the maximum admissible input voltage of the A/D converter. [Reference numerals] (S801) Start; (S802) Set up a direct current offset standard value as a center value of an analog/digital (A/D) converter; (S803) Set up an alternating amplitude gain so that the maximum value of interference signal output does not exceed the maximum admissible input voltage of the A/D converter; (S804) Set up the time constant of an integrator considering an alternating voltage frequency of the interference signal output and the time constant of a output stabilization circuit; (S805) Connect the maximum admissible input voltage of the A/D converter and the voltage of the interference signal output to a peak detector; (S806) Control the gain of the alternating voltage of the interference signal output by the output of the peak detector; (S807) End
