Abstract

A sensor drive includes at least one first seismic mass and an operating apparatus. The operating apparatus is configured to put the first seismic mass into oscillatory motion such that (i) a projection of the oscillatory motion of the first seismic mass onto a first spatial direction is a first harmonic oscillation of the first seismic mass at a first frequency, and (ii) a projection of the oscillatory motion of the first seismic mass onto a second spatial direction oriented at an angle to the first spatial direction is a second harmonic oscillation of the first seismic mass at a second frequency not equal to the first frequency. A method includes operating such a sensor device having at least one seismic mass.
