Analysis of the power coupling efficiency of the relay mirror system with the transmitter composed of sub-telescope array

Model of the relay mirror system with the transmitter composed of sub-telescope array is established. With this model, the new system is theoretically analyzed in the paper. Power coupling efficiencies of the 3-sub-telescope array system and the common system are calculated. The results show that power coupling efficiency of the system with new configuration is significantly improved in comparison with the common relay mirror system.
