Abstract
A method for tuning a sensor coil for a fiber optic gyroscope. The coil is initially wound in a known pattern. One end of the fiber of the wound coil is then adjusted relative to the other end so that a known differential is obtained that effectively displaces the midpoint of the winding pattern. The coil is then attached to an interferometer test apparatus and performance measured. After successive observations a 'trimmed' coil is obtained of acceptable performance characteristics.
