Gravitational wave detection in space

Advance and prospect in the study of laser interferometry technology for space gravitational wave detection

“…除 LISA、太极和天琴计划外，在空间引力波探 测发展过程中，为覆盖不同频段，科学家们提出了不 同轨道、不同臂长、不同原理的探测计划。如覆盖空 间引力波与地面引力波探测间频段空白(0.1~10Hz) 的 DECIGO(DECi-hertz Interferometer Gravitational wave Observatory) [4] ， 臂长更长频段更低的 ASTROD-GW ( Astrodynamical Space Test of Relativity using Optical Devices，Gravitational Wave) ，臂长短探测精 度更高的中频引力波探测 BBO (Big Bang Observer)， 更为宏伟的木星轨道任务 Super-ASTROD，以及地球 轨道的 ASTROD-EM/LAGRANGE、OMEGA 等 [28] 。 空间引力波探测计划主要分为两种轨道结构， 即 日心轨道和地心轨道 [26] 。其优缺点如下：日心轨道的 主要优点是环境稳定性好、三星编队的呼吸角小，主 要缺点是离地球比较远，最近约为5 × 10 [29] 。本章只对干涉 仪系统进行介绍，主要包括激光器、望远镜、光学平 台以及相关的数据后处理系统(相位计) [30] ，各部件 之间的联系如图 4 所示。…”

Orbit optimization and time delay interferometry for inclined ASTROD-GW formation with half-year precession-period

“…The TDI was first used in the study of ASTROD mission concept. [27,28,45] In the deep-space interferometry, long distances are invariably involved. Due to long distances, laser light is attenuated to a great extent is needed.…”

Continuous Low-Thrust Maneuver Planning for Space Gravitational Wave Formation Reconfiguration Based on Improved Particle Swarm Optimization Algorithm

“…In these projects, three or more spacecraft are arranged in an equilateral triangle, and lasers are employed to measure the minute distance variations driven by gravitational waves. Compared with the ground detector, the space-based gravitational wave detector has the characteristics of a long baseline distance, fewer noise and interference sources, and the ability to detect gravitational waves from all directions, which make it especially suitable for capturing weaker gravitational wave signals in medium- and low-frequency bands [ 7 ]. However, space gravitational wave detectors present various challenges in their design and operation, among which the configuration maintenance and control of the precision formation flying is the most fundamental and urgent difficulty [ 1 , 8 , 9 ].…”
