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

摘要

PURPOSE: A simulator for a sagnac interferometer of an optical fiber gyroscope and a simulation method of a sagnac interferometer are provided to perform an optimum design and to detect and correct a sensor error. CONSTITUTION: A simulator for a sagnac interferometer of an optical fiber gyroscope comprises a time delay generating unit(210), a rotation information adding unit(220), and a calculation unit(230). The time delay generating unit delays transfer time of parts of digital signals. The rotation information adding unit adds rotation information to the generated digital signals. The calculation unit performs cosine calculation about the digital signals and produces a digital output signal corresponding to the calculation result.
