ABSTRACT:
As a rotary member is rotated, light images are produced in a radial direction from the rotary member. The light images are produced in time or position division multiplexed fashion so that, although at any given instant, only a portion of an entire image is actually generated, due to the light persistence of an observer's eye, the observer will observe an entire image about the rotary member.
