SENSING COIL FOR FIBER OPTIC GYROSCOPES AND MANUFACTURING METHOD FOR SAME

A fiber optic gyroscope sensing coil, with which winding process of optical fiber may be simplified, crosstalk due to winding deficiencies may be reduced, and temperature sensitivity of gyroscope may be reduced. A coil body 13 includes two potted coils 12 having respective windings of optical fiber which are wound in an aligned winding configuration while the same tension is applied to optical fiber and at the same feed speed of optical fiber between the two potted coils and encapsulated within a potting material 16. The potted coils 12 are united together to form the coil body 13 by adhering the potted coils with each other at respective one side faces 12b thereof by using the potting material 16 as adhesive, and the tip ends of respective first fiber end sections 12c of optical fiber 14 of the potted coils 12, which are guided out from respective outermost layers of the windings of the potted coils 12, are connected with each other by fusing to form a continuous length of optical fiber of the coil body 13 wound in one direction.
