Abstract: An FMCW LIDAR system includes a laser which emits a laser beam and a radiation source which comprises a frequency comb generator. The semiconductor laser may be a VCSEL. The frequency comb generator generates a frequency comb from the laser beam. A beam bundle comprising a plurality of laser beams, each of which has a respective wavelength of λ1, λ2, λ3, . . . λn, or laser mode, is generated from the laser beam having a wavelength λ0. The generated beam bundle is fed to a beam splitter which allows one part of each individual laser beam to pass in the direction of the object to be measured. Another part of each individual laser beam is allowed to pass as a reference beam in the direction of an assembly of detector elements. The system may further include a first grating and a second grating.
