Ultraminiature tactical grade cryogenic RFOG

摘要

An axial gyroscopic pointing reference for mounting on optics within an internally cooled telescope a resonant fiber optic gyroscope, in which the elements of the fiber optic gyroscope are cryogenically cooled with the same system that cryogenically cools the telescope optical elements. In one specific configuration the pointing reference includes three orthogonally positioned resonant fiber optic gyroscopes supported in a tetrahedron configuration and cryogenically cooled by the telescope cooling system.
