(57) Abstract:Usage: optical-mechanical industry. The inventive method is that a visible image is obtained by tracing individual characters on the screen, which is used as clouds or smoke, or fog, a source of electromagnetic radiation, made in the form of a laser system with a controlled beam. The invention relates to the field of information, and more precisely, relates to a method of obtaining visually perceived information.A method of obtaining visually perceived information, namely, that irradiate the screen electromagnetic radiation to produce visible images .In this way irradiate the screen light. However, this method does not allow the transmission of information on a very large area for a large number of people without the use of additional hardware. As the screen in this way use is widely known standard cloth screen.The closest in technical essence to the invention is a method of visually perceived information consisting in tromagnetic radiation .This method does not provide a sufficient brightness of the image.The basis of the invention is to provide a method of obtaining visually perceived information, which due to the particular execution screen, the use of natural phenomena and artificial inhomogeneities in the atmosphere transmits information on a large area for a large number of people without the use of additional technical means enabling high brightness and contrast of the image.The problem is solved in that in the production method of visually perceived information, namely, that irradiate the screen electromagnetic radiation and by izobrazevanje and reflection of electromagnetic radiation from the screen to receive the visible image, according to the invention is used as a screen inhomogeneity of the atmosphere.It is advisable as inhomogeneities in the atmosphere to use clouds, smoke, fog.The method of obtaining visually perceived information is that the screen electromagnetic radiation and through transformation and reflection of electromagnetic radiation from the screen get the visible Sabry can use clouds smoke, fog. Clouds, smoke, fog are the smallest particles of a substance dissolved in atmospheric environment. When the air together with water vapor in it for one reason or another is cooled, the water vapor may condense as water droplets or crystals. The so-formed clouds and fogs. They consist of tiny droplets of water or as tiny particles of ice. The present invention uses the property of light reflection from opaque atmospheric formations.For a better understanding of the present invention are the following specific examples.Irradiate the screen electromagnetic radiation. For example, with a laser beam. The quality of the screen is used, for example, the cloud.On the inhomogeneity of the atmosphere. For example, the cloud, the source of electromagnetic radiation forms a visible image. As the electromagnetic radiation used a laser device with a controlled beam. The beam is scanned in a two-coordinate plane and modeled power. Scanning can be done as a raster, and to draw individual characters. The laser beam is directed to the inhomogeneity of the atmosphere, for example, on the cloud or smoke, or fog. The laser beam is gnosti atmosphere is used as the screen. With this method, the visible image can be observed on a large area. It is necessary for an observer remote from the laser setup for a specified distance, to create the clouds visible image that can be observed with sufficient brightness and size. In this case, assume that the beam divergence is negligible, i.e., the spot size on the cloud is much less than the symbol size, i.e. less than at least 10 times. When this criterion the size of the symbol is the angular size of newspaper font on the best distance vision, while the brightness is magnitude. The observer is located 5 km from the laser system. The laser beam is vertical. The method of obtaining visually perceived information, namely, that the visible image is obtained by irradiation of the screen in the form of the inhomogeneity of the atmosphere by a source of electromagnetic radiation, characterized in that a visible image is obtained by tracing individual characters on the screen, which is used as clouds or fog, or smoke, and the source of electromagnetic radiation is made in the form of a laser system with a controlled beam.

SUBSTANCE: muons of cosmic rays are simultaneously picked up from all directions of the celestial hemisphere first during a preparation phase and then during an exposure phase. The angle of arrival into the installation is calculated for each muon. The angular interval containing values of the obtained angle of arrival values is found.
