In particular the laser is properly designed so that the resonant mode with the highest power level suffers the largest loss. For angular rate values larger than 100 °/s (=360,000 °/h), the fabricated devices, having a perimeter of exceeding 20 cm, is capable to sense the rotation with good linearity. In the range between 19 °/s (=68,400 °/h) and 100 °/s, a lack of linearity is observed. Finally, for X \ 19 °/s some instabilities in resonating modes intensity have been observed and no beat signal has been measured.

When this locking is achieved, the LIA2 output is proportional to the difference between mCW and mCCW . This difference is proporq q tional to the angular rate. The use of this read-out technique requires a very sophisticated laser source providing a stable frequency modulated optical beam with an appropriate frequency resolution. 3 Resonator Length Modulation-Based Read-Out Technique Sinusoidal modulation of the fiber resonator length enables the sinusoidal modulation of resonance frequencies relevant to the two propagation directions [28].
