INTEGRAL-OPTICAL MODULE FOR FIBER-OPTIC GYROSCOPE Russian patent published in 2007 - IPC G02B6/122 G02F1/01 

FIELD: optical engineering.

SUBSTANCE: integral-optical module for fiber-optic gyroscope has case in form of box provided with hermetic outputs and openings. Integral-optical element is mounted inside case on substrate by means of compound. Integral-optical element is joined with fiber light guides. Light guides are withdrawn through openings in transient bushings and in case. Spaces among openings in case and bushings, as well as among bushings and light guides, are filled with compounds being able of hardening at heating and without heating correspondingly. Curves are formed onto parts of light guides inside case, which curves compensate temperature changes. Cavity of case containing integral-optical element is filled with inertial gas or with viscous-resilient polymer and it is closed by cap.

EFFECT: improved reliability of operation; reduced sizes.
