2:

• The method according to claim 1, wherein a control signal, having at least two frequency components, for an acousto-optical element is generated from one frequency spectrum having the at least two frequencies, or from multiple frequency spectra, which together have the at least two frequencies.

3:

• The method according to claim 1, wherein the single-sideband modulation is carried out according to the IQ method.

4:

• The method according to claim 1, wherein the inverse Fourier transform is an inverse fast Fourier transform or an inverse discrete Fourier transform.

5:

• The method according to claim 1, wherein the multiple transmit signals are obtained from the multiple frequency spectra, and wherein at least two of the multiple transmit signals are modulated via the single-sideband modulation onto different carrier frequencies.

6:

• The method according to claim 1, wherein the one frequency spectrum or the multiple frequency spectra are predefined.

7:

• The method according to claim 1, wherein the one or the multiple carrier frequencies are predefined.

8:
