| contents | Space-borne gravitational wave detections raise new questions for heliophysics: how the Sun-Terrestrial space environment affect gravitational wave detection, and to what extent? Space-borne gravitational wave detectors use laser interferometry to measure displacement variations between two free test masses caused by gravitational waves. Space-borne gravitational wave detectors require extremely high measurement accuracy, making it necessary to take into account the effects of space plasma and magnetic field. On one hand, laser propagation through space plasma can induce optical path difference noise, affecting distance measurement accuracy. On the other hand, interactions between space magnetic field and the test masses can generate acceleration noise. This review introduces studies on laser propagation noise and space magnetic acceleration noise in space gravitational wave detection. And this review presents a method, time-delay interferometry, to suppress laser propagation noise. |
