摘要：

Here, in order to improve Raman light phase stability of an atomic interference gravimeter and reduce effects of Raman retro-reflection mirror's vibration noise on measurement accuracy of the atomic interference gravimeter, a vibration isolator for small type atomic interference gravimeter's Raman retro-reflection mirror was designed and fabricated. Its vibration isolation performance was verified using COMSOL Multiphysics finite element analysis and laser interferometer tests. According to the requirements of atomic interference gravimeter for noise control, the vibration reduction effect of the vibration isolator within the range of 60-200 Hz was simulated. Taking the simulation results as the test guide, a scanning laser interferometer and a standard shaking table were used to measure vibration of a Raman retro-reflector loaded on the vibration isolator, the measurement results agreed well with the simulated ones. © 2019, Editorial Office of Journal of Vibration and Shock.
