Three-dimensional cinema and television imaging
Theodor V. Ionescu
The idea
The Romanian Academy of Scientists records a 1936 patent by Ionescu for three-dimensional imaging in cinema and television.
Ionescu explored ways to apply physical principles to practical instruments. His academy biography records a patent for three-dimensional imaging in 1936. This contribution sits within the longer international history of stereoscopy; it does not establish that he invented all 3D glasses or the whole field of 3D cinema.

Separate two drawings of the same object. Different views can give each eye different information.
A simplified principle to explore. This illustration is not a historical replica or a vision test.
