Abstract :
A novel configuration for the optical fibre gyroscope is described which utilises highly birefringent fibre and polarisation mode selection to achieve a stable ¿/2 bias. By operating the system using a combination of both the unbiased and ¿/2 biased Sagnac outputs, the possibility of wide dynamic range operation is realised.
