How to create a "Pepper's ghost" optical illusion
Since we are in spooky season, let's use some old-fashioned science to create a ghostly effect. The Corning Museum of Glass has revealed that the "Pepper's ghost" optical illusion, named after the man who popularized it, John Pepper, first appeared on stage in 1862 and is still used today by amusement parks, scare houses, and other industries. The University of Arizona Wyant College of Optical Sciences defines this illusion as an optical illusion when light from a bright object reaches a transparent material, causing an observer to see a virtual image that appears to float. The trick involves a large pane of glass or plastic tilted at a 45-degree angle, positioned between the audience and a secret area out of view of the audience, which reflects a brightly lit object or actor reflected by the glass. The technique is simple to create and requires a video or image to project. There are professional applications for a Pepper's Ghost, which can also be applied to teleprompters.
