【摘要】:針對(duì)星地激光通信鏈路中,由于星上負(fù)載有限,無法在衛(wèi)星上安裝調(diào)試自適應(yīng)光學(xué)系統(tǒng)來矯正上行接收光束受到的湍流畸變,提出可以使用主動(dòng)式自適應(yīng)光學(xué)系統(tǒng)解決上行光束的矯正的問題。通過室內(nèi)矯正實(shí)驗(yàn)證明了主動(dòng)式自適應(yīng)光學(xué)系統(tǒng)實(shí)現(xiàn)的可行性,同時(shí)為星地激光通信提供了一種改善上行光束質(zhì)量的方法。
[Abstract]:In the satellite-ground laser communication link, due to the limited on-board load, it is impossible to install and debug an adaptive optical system on the satellite to correct the turbulent distortion of the uplink received beam. It is proposed that the active adaptive optical system can be used to solve the problem of uplink beam correction. The feasibility of active adaptive optical system is proved by indoor correction experiments, and a method to improve the quality of uplink beam is provided for satellite-ground laser communication.
