Thus, "the future screen" is a big screen with the quality of the TV-image which is most approached to reality. And if usual kinescopes drop out of consideration of tools for such screen for the geometrical reasons, because of basic inaccessibility of reality of the image the whole class of modern means of display of information disappears: compound screens; plasma, LED panels, etc. They so far also do not apply for the highest level of quality of the TV-image, and though have the big sizes of screens, are intended for the purposes (outdoor advertizing, show business, etc.).
All history of development of television unambiguously indicates the main criterion of quality of the TV-image is its compliance of reality, i.e. the image is closer to real life, the better. Therefore "the future screen" has to be as if "window" to the real world. Two main requirements follow from this general provision: by the sizes of this "window" and on quality of the image. The second requirement is rather difficult and the first will be in detail considered below, and, geometrical, it is very simple: the sizes of the image have to be such that the viewer observed habitual to it in real life the extent of familiar objects. The screen diagonal stated above 2 meters is given for small (inhabited) rooms with linear sizes to 10 meters ("a house television theater"). In this case the TV viewer, for example, will really observe acquaintances to him actors in the television theater as at real theater from the first rows of orchestra seats. At increase in the linear sizes of spectator audiences the screen diagonal also has to increase in proportion; there is no top limit - audiences can be any, for example, stadiums.
make the most numerous group. The rating is carried out by injection through a heterojunction, and also an electron beam. Heterolasers are tiny, have high efficiency. Can work both in pulse, and in continuous the modes. Despite low power they found the application in the industry. They are applied to spectroscopy, optical standardization of frequency, fiber-optic communication lines, to control of a form, interferential strips of deformation, in optiko-electronics, in a robotics, in systems of fire safety
