A quantum tiltmeter based on atomic interference

Abstract

The invention provides a quantum tilt meter based on atom interference. The quantum tilt meter comprises an atom preparation module, an atom interference module and an atom detection module, wherein the atom preparation module is used for producing atoms required by interference measurement; the atom interference module comprises an atom interference unit and a light pulse sequence production unit; the atom interference unit is used for providing an atom interference area, and the light pulse sequence production unit is used for producing a phi / 2-phi-phi / 2 light pulse sequence; the atom detection module is used for detecting the atoms with different internal states after interference is completed. The quantum tilt meter has the advantages that the high-accuracy absolute measuring of the tilt can be realized; the tilt in the two-dimensional direction can be measured, and compared with the tilt measurement in the one-dimensional direction, only the light pulse configuration is needed to be changed, so that the experiment device is greatly simplified.

Description

technical field [0001] The invention belongs to the technical field of atomic inertia measurement, and more specifically relates to a quantum inclinometer based on atomic interference. Background technique [0002] In the past two decades, atomic interferometer technology has been rapidly developed and widely used. Using the quantum properties of atoms with wave-particle duality, many precision measurement experiments based on atomic interference have been developed rapidly and widely. Applied to the measurement of gravitational acceleration g, gravity gradient, rotation, fine structure constant, and Newton's gravitational constant; atomic interference is also used in basic physics, and it can be used to test the equivalence principle and Lorentz violation, etc. Recently, both France and the United States have proposed A scheme for atomic interferometry of gravitational waves. More and more scientists are devoting themselves to the development of cold atom interferometry, a...
