研究了不同序列拉曼光脉冲对原子重力仪灵敏度的影响.结果表明,通过调节脉冲间隔可以改善原子干涉重力仪的灵敏度.在标准配置下,只考虑重力及一阶重力梯度时,三脉冲序列(π/2-π-π/2)的原子干涉重力仪具有较大的灵敏度,四脉冲序列(π/2-π-π-π/2)的原子干涉重力仪对重力不敏感,可用来测量重力梯度,五脉冲作用会降低原子干涉重力仪的灵敏度. The effects of different Raman pulses on the sensitivity of atomic gravimeter are studied.The results show that the sensitivity of atomic interferometry gravimeter can be improved by adjusting the pulse interval.In the standard configuration, only considering the gravity and the first-order gravity gradient, the three-pulse sequence (π / 2-π-π / 2) atomic interferometry gravimeter with greater sensitivity, four-pulse sequence (π / 2-π-π-π / 2) atomic interferometry gravimeter is not sensitive to gravity can be used Gravity gradient measurement, five-pulse action will reduce the sensitivity of atomic interferometry gravimeter.
