Analysis of efficiency of energy transmission in the atmosphere with the use of multichannel optical system

In the paper an analysis is presented of the current state of investigations concerning multichannel laser systems with coherent coupling of signals. The sources of possible aberrations in the system are listed along with the methods of their active and passive compensation. Numeric simulation was used to study the system. Results characterizing parameters of the light field in the plane of observation with different geometry and number of subapertures are included into the paper. Energy transfer by a laser beam was considered in free space.
