  • Torque while turn-around scan mirror assembly
    Patent number: 4047792
    Abstract: A scan mirror assembly wherein the scan mirror performs near-linear cyclic two-way scans. During the useful portion of each scan half-cycle, the mirror is acted on only by the torque of the mounting flexural pivots and at turn-around most of the rotational energy of the mirror is returned thereto by a leaf spring bumper arrangement. A clock controlled "closed loop" torquer operates only during the turn-around period to provide for energy losses by adding that amount of energy required to maintain a scan rate equal to the clock rate.
