<p>A sensor coil (20) for a fiber optic gyroscope. A continuous optical fiber (22) is coated with bonding material (38) of predetermined composition such as a thermoplastic material that exhibits a bond strength of at least 100 p.s.i. in tension, equivalent to at least 40 p.s.i. in shear. The coated fiber (22) is arranged into a predetermined winding pattern whereby contacting portions of adjacent coil turns are bonded to one another. Void spaces (40) between contacting portions of bonded turns reduce the volume of bonding material (38) employed (as opposed to a filled potted sensor coil). The coil (20) does not experience the differential in expansion along the axial and radial directions to the degree that has, for example, required the use of single flanged spools in the prior art. Its use with dual-flanged spools (24) permits mounting arrangements that promote coil stiffness, thereby enhancing gyro performance in the presence of vibration.</p> |
