高精度自由空间光学时频基准传输技术研究进展
摘要
Free space time -frequency reference transfer is the key technology in the application such as global timing and synchronization, high -speed broadband communication, satellite formation flight, and space physical parameter monitoring.The development of optical clock technology puts forward higher requirements for the transfer accuracy of optical time -frequency reference.This paper introduces recent research progress on free space optical time -frequency reference transfer technology, especially the phase and space noise compensation methods based on optical frequency comb carried out by different research institutions, to satisfy the high precision time -frequency transfer under atmospheric turbulence.Finally, the applications using free space optical time -frequency transfer technology are summarized and prospected.
