An illusion transmitter uses two parabolic mirrors to transmit 3-D illusions of an object by use of a camera trained on the first mirror, which then sends video signals to a projector aimed at the second mirror. It was invented by Valerie Thomas; she received a patent in 1980.[1] She developed it for the purpose of sending three-dimensional images across a distance, making them look as if they are in front of the mirror.[2][3] As of 2022, the technology is still used by NASA and is being adapted for use in surgery, as well as for televisions and video screens.[4][5]
