Abstract
In a volumetric display, a strobe source illuminates a moving object at successive instants separated by potentially unequal time intervals. By specifying these intervals, an illumination controller achieves eye-catching visual effects suitable for advertising kiosks or other public displays. The volumetric display includes a signal generator configured to generate a first and second signals. An illumination controller interleaves these signals and provides the resulting interleaved signals to a strobe unit that is disposed to illuminate the moving object in response to the interleaved signals.
