ABSTRACT:
A substantially cylindrical symmetrically wound coil for a fiber optic rotation sensor, having a flat cylindrical disc, with a central aperture, disposed in the center of the coil. A continuous optical fiber of substantially uniform cross section having two substantially symmetrical segments extends through the aperture. A spirally wound first fake of a first segment of the fiber is disposed on one side of the disc in a helical spiral extending from the inner diameter of the aperture of the disc to its outer circumference in closely spaced spiral loops. A spirally wound first fake of a second segment of the fiber is disposed on the other side of the disc in a helical spiral extending from the inner diameter of the disc to its outer circumference in closely spaced spiral loops. A first connecting portion of the first segment of the fiber extends from the outer circumference of the one side of the disc across the outer circumference of the disc and the first fake of the second segment of the fiber. A spirally wound second fake of the first segment of the fiber is juxtaposed on the surface of the first fake of the second segment of the fiber in a helical spiral extending from the outer circumference of the disc to the inner diameter of the disc. A first connecting portion of the second segment of the fiber extends from the outer circumference of the one side of the disc across the outer circumference of the disc and the first fake of the first segment of the fiber. A spirally wound second fake of the second segment of the fiber is juxtaposed on the surface of the first fake of the first segment of the fiber in a helical spiral which extends from the outer circumference of the disc to the inner diameter of the disc. A spirally wound third fake of the first segment of the fiber is juxtaposed on the surface of the second fake of the first segment of the fiber in a helical spiral which extends from the inner diameter of the disc to its outer circumference in closely spaced spiral loops. A spirally wound third fake of the second segment of the fiber is juxtaposed on the surface of the second fake of the second segment of the fiber in a helical spiral which extends from the inner diameter of the disc to its outer circumference in closely spaced spiral loops. The ends of each of the segments of the fiber are adapted for connection to a fiber optic rotation sensor.
