The invention relates to a Cardanic suspension for a sensor having an outer and an inner Cardanic suspension, which Cardanic suspension makes it possible to stabilize vibrations in a wide frequency band without the sensor or the sensor together with the suspension having to be statically balanced. According to the invention, a direct drive (12, 18) is provided for at least one drive of an outer axis of rotation (11, 15) of the outer Cardanic suspension (30) and an amplified piezoelectric actuator (34, 35) is provided for at least one drive of an inner axis of rotation of the inner Cardanic suspension (31), wherein the at least one outer axis of rotation (11, 15) is designed for vibration stabilization in a first range of the frequency band to be stabilized and the at least one inner axis of rotation (24, 27) is designed for vibration stabilization in a second range of the frequency band to be stabilized, wherein the second range of the frequency band to be stabilized lies at least partially above the first range of the frequency band to be stabilized, and wherein the outer Cardanic suspension (30) and the inner Cardanic suspension (31) are designed as a mechanically stiff construction that transmits vibrations in the frequency band to be stabilized in a substantially undamped manner. |
