METHOD FOR IDENTIFYING A SAMPLE IN A CONTAINER, E.G. WHEN CONDUCTING A TRAVELLER SURVEY IN THE CHECK-IN AREA, BY DETERMINING THE RESONANCE FREQUENCY AND THE QUALITY OF A DIELECTRIC RESONATOR TO WHICH THE CONTAINER IS ARRANGED |
摘要 |
The invention relates to a method for identifying a sample in a container, comprising the following steps: the container with the sample is disposed in the form of a resonator; a high-frequency signal is injected into the resonator for exciting a resonant mode of the resonator; the resonant electric field of the resonator penetrates a part of the sample in the container; the resonance curve of at least one resonant mode is measured with and without the sample; the sample is identified on the basis of the determined variation of resonance frequency compared to a measurement without sample. The invention also relates to an associated measuring device. |
