Abstract: An apparatus for producing an image of an object by electromagnetic radiation includes a transmitting device for producing the electromagnetic radiation, a plurality of transmitting antennas connected to the transmitting device for emitting the electromagnetic radiation, a plurality of receiving antennas, which receive the electromagnetic radiation emitted by the transmitting antennas, and a receiving device, connected to the plurality of receiving antennas, for receiving the electromagnetic radiation and a motor-driven rotating scanner. The transmitting antennas and the receiving antennas are arranged on the scanner. The scanner is set up in such a way that the transmitting antennas and the receiving antennas are rotatable at the same speed about an axis of rotation.

Abstract: A method of spectrometry on a spatially extensive sample with generation of a measure in respect of a match of a detected spectrum of a first generation with a single or a plurality of predetermined comparative spectra of chemical substances is disclosed. The method includes the steps: determining at least one location of the first generation on the sample, irradiating the sample with electromagnetic radiation with a plurality of frequencies or a frequency band between 1 GHz and 30 THz at the given location of the first generation of a first order on the sample, frequency-resolved detection of a measure in respect of the intensity of the electromagnetic radiation irradiated on to the sample at the location of the first generation and transmitted or reflected by the sample as the spectrum of the first generation, and calculating a respective measure in respect of a match of the detected spectrum of the first generation with one of the comparative spectra.
