论文摘要
激光干涉仪空间天线（LISA）的目的是通过长期（2.5 mkm）飞船之间的长（2.5 mkm）激光链路检测引力波。除其他要解决的噪声源外，还包括由发射光束的角度抖动引起的相位波动。本文遵循我们的先前的（Vinet et al 2019类。我们在这里对该阶段进行数值处理，以在发出的波前像差中的第一阶处理，但没有对静态偏置项的任何假设。我们验证，在阶段变化中，静态错误点中的高阶项与我们上一篇论文中的结果一致。
The aim of the Laser Interferometer Space Antenna (LISA) is to detect gravitational waves through a phase modulation in long (2.5 Mkm) laser light links between spacecraft. Among other noise sources to be addressed are the phase fluctuations caused by a possible angular jitter of the emitted beam. The present paper follows our preceding one (Vinet et al 2019 Class. Quant. Grav. 36, 205 003) based on an analytical study of the far field phase. We address here a numerical treatment of the phase, to first order in the emitted wavefront aberrations, but without any assumptions on the static bias term. We verify that, in the phase change, the higher order terms in the static mispointing are consistent with the results found in our preceding paper.
