Gravity detection by cold atom interferometer |
|
Abstract |
Atom interferometer has developed rapidly over the past two decades and it is currently one of the most intriguing and promising frontiers of precision metrology, opening up unprecedented prospects. We present a device of Rb 87 cold atom interferometer based on cold atomic fountain. It is used in Gravity detection. Compared with our previous work, an MOT was improved in the detection signal-to-noise ratio. A better optical phase-locked loop system is used to reduce the phase noise of Raman beams. The sensitivity of gravimeter has been improved. |
