Abstract
The disclosure relates to a cold atom interferometry sensor that includes: a source of atoms; a dual-frequency laser capable of generating a first Raman dual-frequency laser beam; a reflector arranged so as to reflect the first Raman dual-frequency laser beam in order to generate a second Raman dual-frequency laser beam, the first laser beam and the second laser beam propagating in different directions in order to obtain atomic interference fringes from the emission of cold atoms obtained from the atom source; characterized in that the reflector is further arranged so as to enable multiple reflections of the first beam on surfaces of the reflector, so that the first beam and the multiple reflections thereof allow the capture of atoms from the atom source in order to obtain the cold atoms.
