METHOD OF SPECTROMETRY AND SPECTROMETER

摘要

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.

1. 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 or a plurality of predetermined comparative spectra of chemical substances, which 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 from a frequency range of 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 by the sample 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, wherein if the calculated measure in respect of the match of the detected spectrum of the first generation with one of the comparative spectra lies in a predetermined region a measure in respect of a match of at least one detected spectrum of a second generation with each of the comparative spectra is generated by performance of the following steps: determining a predetermined number of locations of the second generation so that all locations of the second generation on the sample are different from each other and from the location of the first generation and all locations of the second generation are arranged on the sample in a predetermined region around the location of the first generation, irradiating the sample with electromagnetic radiation with the plurality of frequencies or the frequency band from a frequency range of between 1 GHz and 30 THz at the locations of the second generation on the sample, frequency-resolved detection of a respective measure in respect of the intensity of the electromagnetic radiation irradiated on to the sample at the locations of the second generation and transmitted by the sample or reflected by the sample as spectra of the second generation, and calculating a respective measure in respect of a match of each spectrum of the second generation with each of the comparative spectra.
