Claim:
1. An apparatus for generating and displaying a projected digital image, the apparatus comprising: an actuator; a holographic encoded medium comprising a holographic pattern distributed between a plurality of holographic elements of the holographic encoded medium, the holographic encoded medium disposed in operable communication with the actuator; a light source configured to produce a coherent light disposed in optical communication with the holographic encoded medium; and a controller operable to control synchronization of pulsation of the coherent light from the light source with a position of the holographic encoded medium on a per holographic element basis, the holographic encoded medium driven in motion by the actuator to produce the projected digital image on a projection surface based on directing the coherent light to different portions of the holographic pattern at different times in a predetermined sequence of illumination of the holographic encoded medium by the coherent light that reflects/refracts the coherent light onto the projection surface, wherein directing the coherent light to different portions of the holographic pattern at different times comprises directing the coherent light from the light source at a first time to synchronize pulsation of the coherent light with a first portion of the holographic encoded medium and directing the coherent light from the light source at a second time to synchronize pulsation of the coherent light with a second portion of the holographic encoded medium based on the actuator driving the holographic encoded medium in motion.
