Abstract:
The invention relates to methods and to devices for generating multispectral illuminating light having an addressable spectrum, for adaptive multispectral imaging and for capturing structural and/or topographical information of an object or of the distance to an object. The illuminating device comprises a multispectral light source and a modulator for temporal modulation of the individual spectral components of the multispectral light source having modulation frequencies. The multispectral light source comprises at least one light source having a continuous, quasi-continuous, or frequency comb spectrum and wavelength-dispersive means, or an assembly or array of monochromatic or quasi-monochromatic light sources having emission wavelengths or emission wavelength bands which are different from one another in each case. The modulator comprises at least one electrically controllable three-dimensional light modulator, or a plurality of electronic control modules assigned to the individual monochromatic or quasi-monochromatic light sources.
