Abstract:
A vibration suppressing structure for a fiber optic gyroscope, comprising:a first optical fiber arranged into a first plurality of concentric cylindrical layers, each of the concentric layers having a plurality of turns of said first optical fiber, and each of the turns arranged into a first predetermined winding pattern;a second optical fiber arranged into a second plurality of concentric cylindrical layers, each of the concentric layers having a plurality of turns arranged into a second predetermined winding pattern; anda support structure comprising:a spool for supporting the turns of said first optical fiber and the turns of said second optical fiber; anda circuit carrier attached to a first end of said spool, wherein said circuit carrier is attached to an integrated optical circuit, and wherein:said first and second optical fibers have optical fiber leads fastened to said circuit carrier;said integrated optical circuit has optical fiber leads fastened to said circuit carrier;each of the optical fiber leads of said integrated optical circuit is fastened with a portion of adhering material to said circuit carrier, such that each of the optical fiber leads of said integrated optical circuit is provided a first stiffness relative to said circuit carrier, and the first stiffness decreases with distance from said integrated optical circuit; andeach of the optical fiber leads of said first and second optical fibers is fastened with a portion of adhering material to said support structure, such that each of the optical fiber leads of said first and second optical fibers is provided with a second stiffness relative to said support structure, and the second stiffness decreases with distance from said first and second fibers.
