[0016] The measurement principle of the present invention is briefly described as follows:
[0017] In the present invention, lasers, electro-optic modulators, optical couplers, optical fiber ring cavities, photodetectors, electrical filters, and electrical amplifiers are used to form two bidirectional positive feedback loops. Bidirectional RF / Microwave signal for sensitive rotational angular velocity. At the same time, the phase-locked loop technology is used to control the resonant frequency through feedback adjustment, and lock the RF / microwave signal oscillating in one direction of the loop to a high-precision standard time reference source.
[0018] The invention is based on the photoelectric oscillation technology and belongs to the bidirectional photoelectric oscillation method. The interval of the oscillation loop start-up mode of the photoelectric oscillator is the fundamental frequency f b It is determined by the delay of the loop to the optical signal, that is, ...
