PURPOSE:To make it possible to accomplish efficient mounting of a sensing coil and to make an optical-fiber gyroscope compact by forming the cross-sectional area of the sensing coil in a rectangular or square shape whose corners are rounded. CONSTITUTION:When a sensing coil 11 having the best possible sensitivity is to be mounted in a rectangular parallelopiped case 12, the largest cross-sectional area of the sensing coil is the one of a rectangular shape. When an optical fiber is curved in an extremely small radius, not only the transmission is strikingly increased, but also the fiber might be broken. To avoid this, it is recommendable that the cross-sectional shape of the sensing coil is made to be of rectangular or square shape whose corners are rounded. In this way, the sensing coil can be arranged along the inner surface of the rectangular parallelopiped case with the best possible uselessness. |
