Optically this works in a very similar way to the Pepper's ghost illusion from classic theatre: an image viewable from one angle but not another.īecause the speaker can look straight at the lens while reading the script, the teleprompter creates the illusion that the speaker has memorized the speech or is speaking spontaneously, looking directly into the camera lens. Light from the performer passes through the front side of the glass into the lens, while a shroud surrounding the lens and the back side of the glass prevents unwanted light from entering the lens.
