PLPublished on October 25, 1960 noum * a * 3 / POLSKIEJ RZECZYPOSPOLITEJ LUDOWEJ PATENT DESCRIPTION No. 41294 KI. 21 a \ 32/22 Marian Rogozinski Warsaw, Podska Telewizja three-dimensional The patent has been in force since June 27, 1957. Three-dimensional television equipment uses two separate cameras for pictures [each of the transmitting lamps] and two separate [but connected as well as cameras] cameras receivers, or a receiver with two TV receivers. It is also foreseen the possibility of using two-beam receiver lamps and other quite complex systems. In contrast to the above, a three-dimensional television device, according to the invention, does not differ substantially in the electrical part as compared to an ordinary two-dimensional television device ( flat) and one-color. In the device according to the invention, it is sufficient, on the transmitting side, to add a non-complicated cap, consisting of two 2-quarters of prisms or prisms (or possibly two pairs of cores) or an additional prism (or a pair) or a more complex set of prisms or mirrors. ; finally, in one variant, several lenses may be used instead of the lens. Moreover, a special screen (filter net) should be applied to the screen of the analyzing lamp, made of the superimposition of two, each different color, meshes with patterns of transparent and colored parallel stripes or an analogous screen, made of two screens. a bundle of differently oriented donors, or finally a plain louvre, a transparent part, containing one set of parallel strips. Even simpler, the attachment is on the receiving side, and it consists only of a mesh, similar to that used on the dosing side, but with a larger pitch. and single color. The cost of producing these attachments by adjusting the photographic prints would be a relatively large bowl. The principle of 3D television according to the invention is shown below. On the transmitting side, two different images of a three-dimensional solid or scene fall on two different, inclined at a certain angle self mirrors 1—2 and od- Mp & Epy away from them, or after passing through j &IWSJiiaty; 3 or a more complex mechanical system, it passes through one common lens 4 or through two different lenses 4 and 16. The two lens and large (or prisms) have two different color or polarization filters or directly on their surface (ie, the surface of the glass is suitably colored), or the filters are positioned just a little in the path of incident light rays on the mirrors or prisms. Thanks to this, each of the mirrors or prisms of this pair reflects or transmits the light of only one color (preferably one of two complementary colors, e.g. only red or only zfoephone), adibo light polarized only in one of the mutually polarized planes. The entire optical system is selected so that the images falling on the screen of the transmitting lamp are superimposed on each other. This screen is shielded placed on the path of the light rays as close as possible to the screen, a screen-filtering grid (raster), composed of lines (strips) of parallel and of the same width, arranged with a transformer of two different colors or with differently arranged poland Tinted (so that the adjacent strips of the mesh polarize the light in two mutually perpendicular planes). Another solution may be in the variant with two lenses, as well as in the variants with the arrangement of prisms (or drills) behind the lens (counting in the direction of the light rays) to use an ordinary "transparent" raster, with the filters colored or polarized becomes redundant, because in a generally known manner (used, for example, in three-dimensional cinematography and here on the reception side), projecting images from two points (two objects or one through mirrors or prisms) through raster composed of parallel strips alternately transparent and opaque to a screen placed at an appropriate distance from it, - an image can be obtained in the form of p-film strips, alternately belonging to the images of the right and left eye. When viewing the screen (receiving camera) through this type of screen, you can see different corresponding images with the right and left eye.

Claims

Claims 1. A device for three-dimensional (stereoscopic) television, characterized by the fact that it consists of two coils of different colors or with color filters, placed anywhere in the way of the light rays shining on them, from a prism and a color raster, wherein the transmitting (analyzing) lamp (6 in Fig. 1) receives the image through a grid (raster) (5), composed of a system of parallel transparent strips, alternating red and green, which are projected onto the other grid two images, corresponding to the one seen by the right and left eye, and passing through the system of two spine cups (1, 2), a prism (3) and a lens (4), each of the mirrors reflecting the light of only one color due to its color or filter , one red and one green, and the light forming the image corresponding to each eye will pass through only one hatch of vertical lines of the grid covering the analyzing lamp, giving it on its surface, and thus also on the screen The receiver's image is composed of thin vertical stripes alternating with the images of the right and left eyes, so that these images, covering the entire screen for each eye, will be assumed to be "three-dimensional" (stereoscopic) when viewing They are ejected from the selected places by an appropriately selected and positioned raster, composed of vertical transitions of transparent and opaque, preferably black, lines (stripes).

3. Device variant according to claim A system according to claim 1 and 2, characterized in that, instead of the two mirrors 1 and 2, a system of four mirrors (1, 2, 7, 8 in Fig. 2) or a system of prisms with analogous operation is used.

4. Device modification according to claim An additional lens (16 in Fig. 3) is used instead of the prism (3) or the prism system (9).

5. Device variant according to claim 1 - 3, characterized in that, instead of the additional prism (3), a prism or an array of 10 prisms is used in the light path behind the lens.

6. Device variants according to claims 1, characterized by the fact that, instead of an additional prism (3), a system of two or four pilasl mirrors, or possibly a complex system of mirrors and prisms (especially square prisms), was used in the light path behind the lens (Fig. 4).

7. Device variety according to sieve. A method according to any of the preceding claims, characterized in that two of the mirrors (14 and 15) or prisms are semi-transparent and provided with red and green color filters, respectively.

8. Device modification according to claim A method according to any of the claims 1-7, characterized in that the filters (or surfaces of the mirrors or prisms) and the screen (rasters) have, instead of red and green colors, other, different colors, in accordance with or close to the colors of the mesh.

9. Device modification according to claim A method according to any of the claims 1-7, characterized in that the filters (or mirrors and prisms) and the filaments (rasters) have, instead of red and green colors, polaroids, respectively, oriented so that their planes of polarization are mutually perpendicular. 11.
