Dual-sided pepper's ghost illusion
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).
1. A method, comprising:
projecting a first image from a first image source onto a first side of a holographic screen, wherein the first image reflects off the first side of the holographic screen for a first holographic image in a first direction; and
projecting a second image from a second image source onto a second side of the holographic screen, wherein the second image reflects off the second side of the holographic screen for a second holographic image in a second direction, wherein the first and second images produce a same holographic image in the first and second directions, respectively.
2. The method as in claim 1 , wherein the first and second image sources are located at a floor-side and ceiling-side of the holographic screen, respectively.
3. The method as in claim 1 , wherein the first and second image sources are located at a respective wall-side of the holographic screen.
4. The method as in claim 1 , wherein at least one of the first and second image sources is a video panel.
5. The method as in claim 1 , wherein at least one of the first and second image sources is a video projection system.
6. The method as in claim 1 , wherein at least one of the first and second image sources is at an approximately 45-degree angle to the holographic screen.
7. The method as in claim 1 , wherein the first and second sides of the holographic screen comprise separate first and second holographic screens, respectively.
