Abstract
Systems and methods herein are directed to foil tensioning systems for Pepper's Ghost Illusion. In one embodiment, a roller-based foil tensioning system provides for a holographic foil to be secured to a roller system on two or four sides, rolled outwards, and are then bolted in place, tightening the holographic screen material. In another embodiment, a frame-based foil tensioning system provides for the foil to be secured to a frame system on two or four sides, stretched outwards by expansion of the frame's size (e.g., by a screw jack system), and then bolted in place (while tightened). Illustratively, the foil can be secured to a tensioning system (e.g., the roller system, the expanding frame, or any frame that can be pulled apart) in a variety of manners (e.g., locking strips or snaps and a groove, loops and a rod, two rods with a foil loop, etc.).
