3D 2way TV



This invention describes how a 2 way 3 d video link may be made using a lenticular array and a specialized video link.








L1 is a lenticular array L2 is an identical lenticular array. 1, 2, 3 are the principal axis of typical lenses.

a, b, c are rays. S1 is an array of photo sensitive diodes and S2 is an array of light emitting diodes.

a', b' and c'  are construction lines. O1 is an illuminated object O2 is the virtual object.


During transmission the dot in S1 has to be reflected through the principal axis point to light the correct LED in S2.



The rays on the right hand side appear to come from the virtual object O2, the rays on the left hand side come from the real object O1.


Each point on the virtual object is transformed into an array of points on the flat screen television one in the focal plane of each lens in the lenticular array by the camera.


Before transmission each lens image is reflected about the intersection of its optical axis on the focal plane.


Each lens makes the points on the screen into a parcel of rays which intercept the eye of the observer so that the right eye sees the right stereo image and the left eye the left stereo image.


If the observer moves his head each eye will see a different view of the object making it possible to see round objects.


In the case of two-way TV S1 and S2 are arrays of alternate photo diodes and light emitting diodes connected by telemetry so that the photo diode lights the corresponding light emitting diode.




This system will provide two way live 3 D television via coupled two way video screens


The camera is a light sensitive array with a lenticular array affixed in front of the light sensitive array.


The monitor is a light emitting array with a lenticular array affixed in front of the light emitting array.



A reflection of the image of each lens about its optical axis is required before transmission.



Each screen has the components of a camera and a monitor interleaved so the screen performs both functions at the same time.






The lenticular array as applied to 3 dimensional images is mentioned in the Bible in the parable of the lattice and by Lau, the discoverer of x-ray crystallography.


It is used in still images with barrel lenses but only makes a stereo pair in that instance, as far as I know the camera has not been described before.
