There is an electrical circuit in which the selenium element is included. FIG. 1 shows approximately two selenium elements 7 and 9. When Illumination of selenium element 7, followed by the closure of the corresponding electrical circuit, attraction occurs — the relay is 56 and 56, with antennas 50 and 50 tuned accordingly to the frequencies of the generators 52 and 52 emit electromagnetic energy. When lighting and selenium element 9 emit antennas 50 and 50. Different antennas emit waves of different lengths. Accordingly tuned antennas 5 /, 5 /: -; and 5 / (Fig. 2) perceive these waves; by means of receivers and straightening. 55, 58 and 58, acting on relays 57, 57 and 57, the corresponding electrical circuits are closed, and moreover. the corresponding bulbs 7 and 9 are lit. The combinations of the lit lamps give an image corresponding to the transmitted one. When photographed, the image is captured. Thus can be transferred by dispatch. If a transmitter with a rotating disk of the appropriate type is used, the number of generators, which in this example is equal to twelve, will be reduced to six. Each lit selenium element will simultaneously operate four generators. The receiving device will change accordingly. FIG. 3 shows another radio transmitter. Under illumination, an approximately selenium element 9 closes a corresponding electrical circuit, the potential of point 69 changes and, in this way, a lamp generator 38 is set in operation before the selenium element 9 is illuminated at the generation boundary. The potential of point 69 also changes in the same way, and thus grid 39, at which the generator 38, previously set 4ia at the generation boundary, begins to generate. Janten 50 and 50 emit electromagnetic waves of various lengths. The recommended device according to FIG. 3 — COMPLETE with a lamp acting on a grid of a grid lamp, similar to a device for grid telephone modulation. Correspondingly tuned receiving antennas 5 / and 5D (Fig. 4) receive electromagnetic waves and, through receivers 64 and 64, transmit them to rectifiers 59 and 59, at which the light bulb 9 lights up. And in this case, the transmitter and receiver can be applied simultaneously waves of different lengths for transmitting and receiving one image point. In the case of transmission of images over a linear wire, the antennas are replaced by two or more linear wires. Selenium elements can be replaced by photocells; It is possible to split the transmitting and receiving screens into several corresponding, identically located sections, with approximately the batteries of transmitting and receiving devices synchronously switching to the tires of different sections, which are thus periodically and sequentially active. In this case, the size of the transmitted images, with the same number of emitted waves with a difference of length, can be significantly increased, since the image can be transmitted by transmitting a larger number of points. The subject matter of the invention. An apparatus for electrical telescoping with several photocells in the transmitter and with the same number of signal devices in the receiver, equally spaced along the coordinate system, so that each element is at the intersection of two mutually intersecting wires parallel to one. or another coordinate axis, characterized in that said transmitter wires are connected to cathode installations for generating oscillations of different frequencies, and receiver wires are connected to receiving devices tuned to the same frequencies, respectively, so that each image element is transmitted by a special combination of waves different frequencies emitted simultaneously.
