摘要
A simple interferometer was used to monitor the seismic noise effect on the equivalence principle test using the free-fall interferometric method.The experimental result showed that this effect was belowλ/100,whereλis the wavelength of the laser beam,and the uncertainty of the differential gravity acceleration of the individual free-fall result due to this effect was about 0.6μGal.
