FIELD: physics, measurement. ^ SUBSTANCE: invention is related to the field of fibre optics and may be used in design of fibre-optic gyroscopes and other detectors of physical values on the basis of ring fiber-optic interferometre. On coil frame having shape of cylindrical shell with flanges on ends, in flanges from both sides, opposite to each other, there are sector-like cylindrical grooves arranged at the depth equal to flange thickness. Detachable crescent-shaped inserts are installed via cylindrical grooves on external surface of cylindrical shell, and then light guide is wound. After winding detachable inserts are removed. Between cylindrical shell and light guide turns, through crescent-shaped gaps are created, which compensate mechanical stresses in turns of light guide. ^ EFFECT: improvement and increase of parametres stability in fibre light wound on frame of fiber-optic gyroscope coil frame. ^ 4 cl, 10 dwg |
