Paper Abstract

The adaptive optics(AO) technology is adopted in the demo experiment of indoor space laser communication system. In transmit terminal, 650nm beacon and 1550nm signal beam with OOK modulation propagate through atmosphere turbulence simulator which simulate the laser's propagation in real atmosphere conditions. The AO system corrects real time wave-front information. In received terminal, signal intensity is collected and the bit error rate(BER) is recorded. Experiment data is obtained in different status of the AO system. Combined with signal beam wave-front reconstructed and image quality of far-field laser spot, results show that the received average power of communication system increases when using the AO system to correct low-order aberration. Also it rejects signal fading and makes the BER lower.
