Abstract

See full text

A detachable framework used for winding optical fiber coils and a method of producing optical fiber coils with this framework. A framework with a suitable structure is designed considering comprehensively three factors, i.e., the window ratio of an optical fiber coil, the precision of an optical fiber gyro and the easy detachment of the framework from the optical fiber coil. A surface treatment with the framework is performed by coating a layer of thermosol on the surface of the framework so the optical fiber coil can be easily detached from the framework after curing. The required length of optical fiber is winded around the optical fiber coil framework, accompanying with vacuum pressure impregnating with curing adhesive after winding and optical fiber coil curing subsequently. The framework is taken off from the optical fiber coil under the heating circumstances, thereby completing production of the non-framework optical fiber coil.
