Aviation and Space Instrumentation St. Scientists of the State University of St. Petersburg revealed how to create a super -centered laser beam for a better connection in space. This will help to increase the range and reduce the energy consumption of space communication systems. This “Gazeta.ru” was told in GUAP.
Experts used crystals grown by the Inorganic Chemical Institute of RAS to scan the bundles of light that are not subject to an optical phenomenon such as crushing in the empty space. Difraction affects the properties of the package, especially the deviation. The larger the distance, the stronger the deviation of the beam and the worse the quality of communication: Additional methods of improving the sensitivity of recipients are required to process signal.
The GUAP team created an experimental example of the Acustooptic device. This is a special device that extensively controls the intensity and application of light beams, and allows you to move and scan this bundle in space. The example was tested in real conditions.
“Existing cosmic communication systems work on traditional Gauss optical beams. However, in cosmic communication systems, it is necessary to ensure the high accuracy of mutual assignment and transmitter. It can be applied to implement transmission systems on the outside in the outside area, which allows you to reduce power consumption, basically non -species.
A doctor before He called him Smells that can increase concentration and efficiency.
