Abstract
Systems and methods herein are directed to a dual-sided Pepper's Ghost Illusion is shown and described. In particular, various embodiments are described that allow using multiple image sources (e.g., projected bounces and/or panel displays) so the holographic image can be seen from both sides of the holographic system. In one embodiment, a specifically designed “Z frame” may be used to minimize the visible components in such a dual-sided system (e.g., particularly for smaller displays).
