GROUND-BASED LASER OPTICAL COMMUNICATION NON LINE OF SIGHT AT 1064 NM WAVELENGTH

The main advantage of optical line-of-sight communication is the ability to transmit data at high speed. In this case, communication is possible only between a small number of subscribers in a localized part of the space. Optical communication non-line-of-sight allows data transmission between an unlimited number of subscribers and with various configurations of communication schemes. We have created and patented an optical communication system outside the line of sight at a wavelength of 1064 nm. It is shown that in the evening it is possible to transmit data through a plume of smoke at base distance of 3.45 km with fixed geometric parameters of the receiving and transmitting system with a symbol error rate of not more than 0.02.
