SIMULATOR OF SAGNAC INTERFEROMETER OF FIBER OPTIC GYROSCOPE AND METHOD OF SIMULATION OF SAGNAC INTERFEROMETER

摘要

The present invention relates to a method for simulating a sagnac interferometer simulator, a sagnac interferometer simulator, and a sagnac interferometer of an optical fiber gyroscope. A time delay generator for delaying the transmission time of at least some of the digital signals to correspond to the delay, and rotation information corresponding to the phase difference of the lights generated by the rotation of the optical fiber gyroscope to the digital signal generated from the time delay. And a calculation unit for performing a cosine operation on the digital signal to which the rotation information is added, and generating a digital output signal corresponding to the result of the operation. Through this, the present invention can easily evaluate the performance, sensitivity, etc. of the sagnac interferometer according to the change of the design variable. ; Gyroscope, sagnac, simulator
