چکیده
Abstract Information on the Earth’s gravity provides significant strategic support for economies, defense and security. An atomic gravimeter (AG) realizes highly precise measurements of gravitational acceleration by virtue interference. Vibration noise is a strong contributor to limitations measurement sensitivity accuracy an AG. compensation methods thus enhance environmental adaptability AG since it can facilitate when isolation platform unavailable. A dynamic filter here devised correction data output from seismometer, which expands bandwidth seismometer lowers distortion vibration signals. Additionally, transfer function estimation introduced better reflect actual Raman mirror. Based simplified model, this method modify interference fringes in real time. The experimental results show that proposed optimization attenuate cosine fitting phase uncertainty up 85.91%, reach about 76.37 μGal complicated environment. AG’s effectively improved method. It verified effective adaptable

A New Method for Time-Delay Compensation in Control Systems
In this paper a new method is introduced and investigated for removing the destabilizing effects of time-delay parameter in control loops. The concept of the method is taken from the knowledge concerning the dynamic behaviour of irrational transfer functions (Ir-TF), which is discussed and investigated elswhere in frequency response domain and is explained briefly here. Ir-TFs, which are we...

متن کاملDouble diffraction in an atomic gravimeter
We demonstrate the realization of a new scheme for cold atom gravimetry based on the use of double diffraction beamsplitters recently demonstrated in [1], where the use of two retro-reflected Raman beams allows symmetric diffraction in ±h̄keff momenta. Though in principle restricted to the case of zero Doppler shift, for which the two pairs of Raman beams are simultaneously resonant, we demonstr...
