FAQ

What is RFOG, Brillouin gyro, and RFLG?

The fiberoptic ring resonator gyroscope (RFOG) consists of a recirculating passive optical cavity. The cavity resonant frequency is modulated by the angular rotation. The change in the resonance frequency of the counter propagating waves is simply transformed into a variation of the output power from port 4 of the fiber optic coupler.

This configuration thus operates as a high finesse fiber ring resonator. Since the finesse F enhances the sensitivity, good performances can be obtained with a much shorter fiber length (of a factor approximately F). While the RFOG maintains the passive structure of the IFOG, stimulated Brillouin scattering has been investigated for an active fiber ring resonator. This approach exhibits in principle the capability of high performances mainly because of the reduced negative effects induced by nonreciprocity and non ideal behavior of the employed components.

The FRLG (fiber ring laser gyro) takes advantage of the rare-earth doped fibers as the active medium sustaining the laser oscillation in the sensing coil. The configuration is similar to the RFOG of Figure 16.13, but now the coupler is a WDM (wavelength division multiplexer) fiber-coupler, arranged so as to cross the pump power (at a wavelength λpump) from an external laser-diode, and to bar the oscillating field in the ring (at λsig). In this way, a very high ring finesse can be attained, and by controlling the oscillating modes, a working situation similar to the He-Ne RLG is pursued. Non-idealities of the fiber, however, have prevented to achieve avionic-grade sensitivities so far.
