Twin-lattice atom interferometers promise compact, large area devices for rotation measurements in inertial navigation. We aim at developing a compact and portable demonstrator capable of multi-axis inertial sensing, enabling precise measurement of rotations and accelerations. In future, an experimental realization of multi-loop atomic interferometry using such a portable gyrosope is also possible.
We present a brief theory of twin-lattice atomic Sagnac interferometry, the current status of the preliminary system design of the demonstrator using the Bose-Einstein condensates (BECs) of 87Rb atoms. We also present the design of the laser system for beamsplitter, cooling and detection sequence.
