Abstract: A gimbal mounted mirror, universally tiltable about coplanar coordinate axes, reflects a sight image onto a screen of an optical weapon sight. Four linear electrodynamic motors, two for each tilt axis, control mirror positioning. The motors are on said axes, equidistant from their intersection, and spaced far enough from that intersection so that a mirror position transducer can be located between them, under the gimbal mounting. The transducer comprises a soft iron rotor carried by the mirror, a central core wound with an a.c.-energized exciter coil, and four outer cores that are positioned like the motors and each wound with a secondary coil.
