Illusion transmitter

An illusion transmitter uses two parabolic mirrors to transmit 3D 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, for which she received a patent in 1980.[1] She developed it for the purpose of sending three-dimensional images across a distance, making them look like they are in front of the mirror.[2] The technology, still in use by NASA, also enabled the creation of magnetic resonance imaging and 3-dimensional television.[3]
