Abstract :
A method for reducing the Shupe effect in fibre-optic gyros is described, and verified experimentally. The unbalanced phase shifts in the gyro Sagnac intereferometer that are produced by a traversing temperature gradient are randomised by winding the coil in such a way as to scramble the relative positions of the turns
