Abstract
The invention features a volumetric display system including an optical relay, a motor, a support structure coupled to the motor, a projection screen disposed on the support structure, and a projection optic. During operation, the projection optic receives a light beam from the optical relay and projects the light beam onto the projection screen. Also, the motor rotates the support structure, the projection screen, and the projection optic about a rotation axis.
