Dither applied to ring laser gyroscopes in order to counteract lock-in results in an unwanted signal that appears in the gyroscopes output. The invention is a way of reducing the unwanted signal due to dither. The proposed solution comprises decoding the gyroscope output signal into respective signals which represent clockwise and counter-clockwise motion, delaying a portion of each of these signals, and combining the delayed and non-delayed signals to derive an output representative of rotation of the gyroscope-the dither having a reduced effect on the output.
