Method and signal generator for controlling an acousto-optical element, microscope with an arrangement comprising the signal generator and an acousto-optical element

A method for generating a control signal, having at least one frequency component, for an acousto-optical element, from one frequency spectrum having the at least one frequency, or from multiple frequency spectra which together have the at least one frequency, the method comprising:

• obtaining, from the one frequency spectrum or from the multiple frequency spectra, one transmit signal in the time domain in each case via an inverse Fourier transform;
• modulating the one or the multiple transmit signals via a single-sideband modulation onto a carrier signal having a carrier frequency in order to obtain one modulated signal in each case;
• and
• obtaining the control signal as a real part of the one modulated signal or as a consolidation of the real parts of the multiple modulated signals,
• wherein the single-sideband modulation is carried out according to the IQ method.
