Patent ID: 7982469

Claim:
A method for measuring an object to be measured by means of radio-frequency electromagnetic radiation, comprising: applying radio-frequency electromagnetic radiation to at least one resonator, the resonance frequency of which is affected by a measured characteristic of the object to be measured; receiving radio-frequency electromagnetic radiation from the at least one resonator; searching the received frequency band for a resonance frequency of the at least one resonator in order for measuring a characteristic to be measured; applying radio-frequency electromagnetic radiation to at least two of the resonators which are directed towards one another and between which the object to be measured is to be placed; scanning the radio-frequency electromagnetic radiation frequencies applied to the at least two resonators over desired frequency bands by using discrete measuring frequencies, the forming of which utilizes digital synthesis; and controlling one resonator of at least two of the resonators such that scanning proceeds from low to high frequency; and controlling a second resonator of at least two of the resonators such that scanning proceeds from high to low frequency.
