  • Volumetric 3D display
    Patent number: 10401636
    Abstract: A drive system for a projection screen in a swept surface volumetric 3D display is disclosed. The drive system causes the projection screen to reciprocate through an excursion distance at a screen reciprocating frequency relative to a projection system. The drive system includes an actuator arrangement for generating an input reciprocating force substantially at the screen reciprocating frequency through an input excursion distance and a support structure for the projection screen. The support structure includes a resonant mounting arrangement for the projection screen. The resonant mounting arrangement is operably connected to the actuator arrangement and configured to allow the projection screen to reciprocate through the excursion distance. The resonant mounting arrangement is configured to have a resonant frequency substantially equivalent to the screen reciprocating frequency on actuation of the actuator arrangement.
