METHOD AND DEVICE FOR GENERATING MULTISPECTRAL OR HYPERSPECTRAL LIGHT, FOR HYPERSPECTRAL IMAGING AND/OR FOR DISTANCE MEASUREMENT AND/OR 2D OR 3D PROFILE MEASUREMENT OF AN OBJECT BY MEANS OF SPECTROMETRY

摘要

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.
