The Canterbury Ring Laser, built in the Department of Physics principally by Morrie Poulton and Clive Rowe under the guidance of Professor Hans Bilger of Oklahoma State University, is a large laser gyroscope with an unusually high frequency resolution... The Canterbury ring system has a nearly square optical cavity with an area of 0.7547 square metres and a perimeter of 3.477 m (and so a free spectral range of 86.22 MHz). 2, record 5, English, - square%20optical%20cavity%20laser%20gyro

Ring laser gyro... The mechanical structure integrity of the gyro is based on a 1. 2 X1. 2 meter block of zerodur. The zerodur is a glass ceramic material with a thickness of 180 mm weighing approximately 600 kg. The block has four 1-meter longitudinal bores provided for the laser beam paths. Folding mirrors are mounted at each of the four corners of the block. This forms a closed square resonator in which the laser beams can travel in both directions. The block was produced by Zeiss Glaswerke of Mainz, Germany. At Zeiss the machining process included cutting the gyro body edges in preparation for the mounting of the folding mirrors. The surfaces for the mirror mounting are optically polished allowing the folding mirrors to be attached directly to the zerodur by optical contact rather than by bonding. 3, record 6, English, - gyro%20body

Pour l'utilisation sur les centrales inertielles, il s'est révélé nécessaire de développer des gyroscopes présentant une dérive pratiquement négligeable. Or la cause principale de cette dérive réside dans les frottements qui s'exercent sur le corps du gyroscope, dont la vitesse de rotation dépasse 20 000 tr/min. 2, record 6, French, - socle
