ABSTRACT:
A quadrupole-wound sensing coil for a fiber optic gyroscope and a method for forming such a coil. Layer pairs wound from two supply reels terminate with three concentric turns adjacent distinct home flanges. The concentric turns form borders at the ends of the wound layers and bridges to new layers to be formed so that fiber pinching and undesirable microbends are avoided while packing density is enhanced.
