摘要： A spool for receiving a fiber optic sensor coil includes a single, substantially-planar mounting flange and a central hub. The coil can be directly wound upon the hub. The coil is mounted transverse to the plane of the mounting flange and is unconfined in that direction as the surface of the hub is substantially non-adhesive with respect to the inner layer of the coil. This allows axial coil expansion with increases in temperature without generating gyro bias errors. The device is also substantially free from vibration-induced bias errors due to the relatively high resonant frequency (vis a vis environmental vibration) of the integral spool-plus-coil structure.
