Abstract
A fiber optic gyroscope sensing coil having two parts one wound clockwise and the other wound counter-clockwise from a central point on a spool towards ends thereof and back towards the center before crossing over each other and being wound out and back a plurality of times. Such an arrangement has the advantage of eliminating the temperature sensitivity of such coils and reducing microbending of the fibers thereby producing a more accurate coil for a fiber optic gyroscope. Preferably the outermost layer of fiber is a single layer.
