Beschreibung
Zusammenfassung:	The invention relates to a cold-atom and light-pulse interferometric system (100) comprising a vacuum chamber (7) containing a cloud of cold atoms (8), a planar retro-reflective optical component (5), a laser source (6) suitable for generating a sequence of laser pulses, and a detection system (17) able to perform an inertial measurement by atom interferometry. According to the invention, the interferometric system (100) comprises an actuating device (13) that mechanically connects the optical component (5) to a plate (4), and a rotation sensor (1, 2) which is suitable for providing a measurement of the rotation of the vacuum chamber (7) about an axis transverse to the axis of the laser at each interrogation time in said sequence, the actuating device (13) being able to angularly incline the optical component (5) relative to said plate (4) during each interrogation time in said sequence on the basis of said rotation measurement.
