Modeling a Large Ring Resonator Gyroscope.

Abstract

The results obtained can be divided into three categories: a) A feasibility study with focus on quantum noise and low frequency noise b) Basic modeling of the ring with Gaussian beam and ray matrices c) Technical design: Effect of residual gas in ring on quality factor and light drag, scanning of beam, effect of misalignment and mismatch of source to ring, calibration procedures. The results show no obstacle yet to the goal of acheiving a sensitivity of rotation rate of better than 10 to the -19th power (earth rate) in rings of 60 sq m size. Such a sensitivity which corresponds to a change of earth surface velocity of smaller than 4 cm/day, should surpass Lunar ranging methods, Lageos methods as well as VLBI-methods in accuracy, besides being a 'real time' observational method for earth rotation.
