In Victorian times a suggestion of a three dimensional image could be achieved with a lenticular array. In this suggestion a lens array may be used to allow a two way screen for 3-D viewing, both ways.
See Diagram
I suggest that a three - D image may be built up of image points on an array of small screens behind an array of converging lenses. Each lens takes a point in its image plane and makes a parallel ray of light from this point.
The images are made up by an array of lenses where the image on a photosensitive screen is the right way up and not laterally inverted.
In order to make this optically each lens has two elements, a converging lens L1 and a converging lens L2. L1 makes an inverted real image which is brought into focus by a converging lens behind it.
See Diagram
This right way round image is sent by radio to the viewing array.
See Diagram
An array of alternate Cameras and Viewers makes up the viewing screen. See Diagram
A patent for this idea was abandoned by me many years ago because of lack of resources.
