Sensor Coil For Low Bias Fiber Optic Gyroscope

View page
US Patent:
53715934, Dec 6, 1994
Filed:
Aug 31, 1992
Appl. No.:
7/938294
Inventors:
Amado Cordova - West Hills CA
Donald J. Bilinski - Northridge CA
Samuel N. Fersht - Studio City CA
Glenn M. Surabian - West Hills CA
John D. Wilde - Woodland Hills CA
Paul A. Hinman - San Pedro CA
Assignee:
Litton Systems, Inc. - Beverly Hills CA
International Classification:
G01C 1972
US Classification:
356350
Abstract:
A sensor coil for a fiber optic gyroscope. The coil is formed on a spool of carbon composite material or of another material whose coefficient of thermal expansion approximates that of the overlying windings of the glass optical fiber. The windings are potted in an adhesive material. Various bias effects are addressed by the coil design. The close matching of the thermal expansion characteristics of the spool and the fiber windings as well as proper selection of the coil potting material minimize the Shupe-like bias caused by thermal stress that would be otherwise exerted by a standard metallic spool. By careful selection of potting material (particularly its modulus of elasticity) vibration-induced bias, coil cracking, degradation of h-parameter and temperature-ramp bias sensitivity are also minimized.

Gyro Sensor Coil With Low-Friction Hub Interface

US Patent:
55458920, Aug 13, 1996
Filed:
Sep 1, 1994
Appl. No.:
8/299585
Inventors:
Donald J. Bilinski - Northridge CA
Gene H. Chin - Los Angeles CA
Amado Cordova - West Hills CA
Samuel N. Fersht - Studio City CA
Assignee:
Litton Systems, Inc. - Woodland Hills CA
International Classification:
G01D 534
G01B 902
US Classification:
25023112
Abstract:
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.
