FIELD: physics.
SUBSTANCE: radiation-resistant single-mode light guide with a large linear birefringence for a fiber-optic gyroscope contains a light-conducting core and a reflective shell consisting of doped quartz glass, an outer protective shell consisting of pure quartz glass, two loading zones with reduced quartz glass of the protective shell with a refractive index and a protective-hardening coating. Herewith the reflective shell of the light guide is formed from quartz glass with a reduced refractive index relative to the refractive index of quartz glass of the protective shell, equal to the refractive index of the loading zones with accuracy ±2×10-3. 1.3≤τ/ρ≤4.6 is provided, whereτ - the radius of the reflecting shell, andρ - radius of the light-conducting core.
EFFECT: high accuracy of the fibre-optic gyroscope.
