<p>A ring laser gyroscope is provided with a readout arrangement in which its two readout beams (5,6) are combined and the polarisation thereof modified such that a sngle combined beam (18) is provided having linear polarisation the plane of which rotates as a consequence of change of phase difference between the readout beams (5,6), and thereby corresponds to the rate of rotation of the ring laser gyroscope.</p> |
