MESURE PAR INTERFEROMETRIE ATOMIQUE AVEC PLUSIEURS ESPECES D'ATOMES

摘要

The invention relates to a method for measuring an external parameter (a) by means of atomic interferometry using two sets of atoms (11, 12) that belong to different species. Two measurements are taken simultaneously at the same location, but independently from one another, in order to obtain two measurement results (P11, P12). Constant phase shifts that appear in the atomic interferences for the two atom sets are quadrature-adjusted in order to ensure that one of the two measurements provides a value for the external parameter with satisfactory accuracy.
