Abstract

PROBLEM TO BE SOLVED: To obtain an optical fiber coil for detectors hating a stable temperature characteristic, by adopting a bobbinless-type optical fiber coil without a bobbin, for a cylindrical optical fiber coil section. SOLUTION: If the shape of a bobbin 1 in figure A is changed as shown in B and C, the bobbin 1 is detached from a cylindrical optical fiber coil section 3. And the bobbin 1 and the cylindrical optical fiber coil section 3 are separated completely, and an optical fiber coil for detectors composed only of the cylindrical optical fiber coil section 3 can be obtained. Besides, it is possible to facilitate shape maintenance of the cylindrical optical fiber coil section 3 after the removal or the bobbin 1, by spraying silicon onto the cylindrical optical coil section 3 and forming a silicon film, before removing the bobbin 1 from the cylindrical optical fiber coil section 3.

The conventional optical fiber coil for a detector has the following problems because it has been configured as described above. That is, since the optical fiber is wound around a bobbin formed of aluminum or the like, the polarization characteristics of the optical fiber fluctuate due to heat conducted from the bobbin, side pressure received by thermal expansion of the bobbin itself, and the like. In such a case, a drift has occurred in the output of the optical fiber gyro.
