ABSTRACT:
The present invention is based on the knowledge that the advantages of a moveable dispersive element with regard to the simple detector element and the adjustability of the measurement range and the resolution can also be used in a miniaturization of a spectrometer, when the dispersive element is operated generally in resonance instead by a quasi-static drive. A proposed spectrometer comprises a vibratably suspended dispersive element for spectrally decomposing a light beam, whose spectral distribution is to be determined, into spectral components, a means for putting the vibratably suspended dispersive element into a vibration with a frequency, which is in such a ratio to the natural frequency of the vibratably suspended dispersive element that a resonance amplification of the voltage of the dispersive element occurs, and a detector for detecting a spectral component of the light beam.
