The rotor is mounted in a frame 3 which is in turn mounted for rotation in shafts 4, 4', the frame being held in neutral position by springs 9, 9' and its movements being damped by a dashpot 10. The markspace ratio of the output from the head 15 is measured by comparison with the number of pulses of a stable time-base oscillator which is independent of the rotor in the case of a rate-of-turn gyroscope, but which is associated with the rotor where it is only desired to measure the precession angle, e. g. by deriving the pulses from means carried by the equator of the rotor. In an alternative embodiment Fig. 2 (not shown) the non- reflecting zones are in the form of curvilinear triangles 16, 16' and two heads 15, 15' are used. In place of the optical reading heads, magnetic heads may be used with correspondingly suitable zones arranged on the rotor 1.
