ABSTRACT:
An apparatus for detecting deflection of the spin axis of a gimbal supported spinning mass relative to the gimbal axis comprises four equally spaced linear arrays of detector elements mounted around the gimbal axis and extending parallel to that axis. Four light sources are provided, each one in alignment with a respective one of the arrays, and a reflective surface is provided on the spinning mass for reflecting light onto the respective detector arrays. Deflection of the spin axis will be registered by displacement of a reflected light spot in one or more of the arrays.
