METHOD OF SUBSTANCE REMOTE SENSING AND IDENTIFICATION Russian patent published in 2008 - IPC G01R33/20 

FIELD: physics.

SUBSTANCE: method of substance remote sensing and identification using remote magnetic resonance initiated by two series radio pulses followed by substance excited radiation (response) frequency measurement value of which indicates this substance, implies that substance is additionally irradiated by the third radio pulse with electromagnetic oscillation chirp filling at frequency which is much greater than substance magnetic resonance frequency. The third radio pulse start concurs with the second radio pulse end, and the third radio pulse end concurs with response end. Response is registered at frequency which differs from the third radio pulse filling frequency by value equal to sensed and identified substance magnetic resonance frequency.

EFFECT: extended range of remote sensing and identification of required substance.
