A TRANSPARENT PICTURE TUBE SCREEN FOR A COLOUR TV RECEIVER FOR DISPLAYING A THREE-DIMENSIONAL TV IMAGE OF A THREE-DIMENSIONAL OBJECT THEREON

摘要

A transparent picture tube screen for a colour TV receiver for displaying a three dimensional TV image of a three-dimensional object thereon, the said screen having vertical microstrips coated with monochrome phosphor material, the microstrips being disposed at three differential planes so as to display the images corresponding to three video signals at three different depth and thus enable a three-dimensional image of the object to be visually reconstructed thereon, the said video signals being produced and transmitted by means of three identical monochrome TV cameras disposed adjacent to each other, the fiscal planes of the cameras being adjusted to respectively pass through the rear, the middle and the front regions of the object; removing the blurred or out of focus regions and reconverting into video signals in analog form before transmitting the said video signals on frequency division multiplex basis to the said colour TV receiver in the known way, the said video signals being capable of projection from three electron guns of the said receiver on to the said screen through a shadow aperture mask.
