Title:
TRAPEZOIDAL COIL FOR FIBER OPTIC GYROSCOPES
Document Type and Number:
WIPO Patent Application WO2002093594
Kind Code:
A8
Abstract:
A trapezoidal bobbin 100 for providing a foundation for a coil of optical fiber comprises an elongated hub 106, an upper flange 102 and a lower flange 104. The elongated hub includes a longitudinal axis AX, a first end, a second end and an exterior surface 110. The hub is symmetrically disposed about the longitudinal axis. The upper flange is disposed at the first end of the hub, and includes an exterior surface that is substantially perpendicular to the longitudinal axis and faces away from the hub. The upper flange is further includes an exterior surface 122 that forms an angle of substantially 60 degrees with respect to the longitudinal axis. The lower flange is disposed at the second end of the hub, and includes an exterior surface that is substantially perpendicular to the longitudinal axis and facing away from the hub, and an interior surface forming an angle of substantially 60 degrees with respect to the longitudinal axis.
