ABSTRACT:
An inertial measurement instrument including a gyroscope utilizes fiber optics to measure gyro rates in two orthogonal axes. Bender beam fiber optic transducers are mounted on a rotating shaft and signals representative of force effects on the bending beams are provided at the rotor in an optical format. The signals are then optically transmitted to the stator thereby eliminating the need for slip rings and the like.
