The paper discusses the modern state of optical resonator gyroscopes. The basic concept of this type of gyros is described. The main approaches to their design and the method for angular rate measurement are considered, with the main focus made on the pioneer and most popular approach based on the use of phase modulation spectroscopy and a tuned laser. An alternative approach based on low-coherent sources of light is also analyzed. The main sources of measurement errors and the methods to overcome them are considered. The best value of random drift has been so far achieved using fiber ring resonators: 2.0 deg/h with the ring diameter 60 mm and the integration time 1 s, and 1.23 deg/h in 5 s; with the diameter 120 mm, 0.37 deg/h has been achieved with the integration time 1 s and 0.06 deg/h with 370 s. The reasons that currently hinder the commercial development of optical resonator gyros are studied. [ABSTRACT FROM AUTHOR] |
