The projector displays threee-dimensional structures or movements and consists of several CRTs, whose number depends on the testing of the best formed of the projection chamber. It has at least one vacuum chamber, a projection chamber, and a luminous gas, or mixt., for filling the projection chamber. There is a microprocessor for storage of recordings of three-dimensional objects. The microprocessor scans the lines of each image from top to bottom. The CRTs are so guided that their electron beams intersect at points to be imaged. Thus the points are lit up via the luminescent gas. Then the image lines are scanned at a rate of approx. 20 images per min. ADVANTAGE - Improved three-dimensional display.
