摘要	To evaluate inhibitory effect of diversity transceiver technology on the atmospheric turbulence in the application of offshore laser communication system, experiment verification scheme of multichannel synchronous acquisition of laser spot based on 1550 nm was designed. Extraction of target center position and target gray statistical of real time image processing system were realized by using terminal triggered with the FPGA+multi-core DSP architecture, and then the arrival angle fluctuation variance and the scintillation index from the laser transmitting terminal to the receiving terminal were obtained. Under the conditions of equal power, arrival angle fluctuation variance and the scintillation index were compared between single way transmitting and double way transmitting, double aperture receiving and equivalent single aperture, and the effect of double aperture receiving was compared under different spans. Experimental results show that the same transmitting power, the arrival angle fluctuation variance and the scintillation index are effectively inhibited caused by atmospheric turbulence with dual way transmitting compared with single way transmitting; in condition of same reception area, the arrival angle fluctuation variance and scintillation index is more weak through single aperture receiving compared with double aperture receiving. In a certain range, double size span exists optimal values. 2016, Editorial Board of Journal of Infrared and Laser Engineering. All right reserved.
