摘要 相干光通信高效率混频这几年已成为国内外研究热点。论文针对空间相干激光通信系统中零差BPSK调制方案的检测灵敏度,研究了准直失配对本系统的混频效率的影响,得到了准直失配可以导致混频效率的严重下降,即系统性能的严重下降。该研究对空间激光相干通信相关工程实验具有重要指导意义。 High efficiency mixing in coherent optical communication become a focus in recent years. We focuses on the detection sensitivity of the homodyne BPSK modulation scheme of the space coherence laser communication system, and study the effect of collimating mismatch on the mixing efficiency for this system. Collimating mismatch can lead to a serious decline of the mixing efficiency. So the system performance seriously declines. This study has important guiding significance to space coherent laser communication engineering experiments.
