Abstract: An improved system for interfacing with a subject material is provided where an interface material having target atoms with a known nuclear quadrupole resonance frequency is purposely associated with a subject material. An excitation signal is used to cause a nuclear quadrupole resonance of the target atoms and a receiving devices receives a received signal comprising a probe signal energy. A signal sampling device samples the received signal to produce detection data that is used for at least one of detecting the subject material, locating the subject material, tracking the subject material, or conveying information.

Abstract: An improved system for sensing includes a first signal source for producing an excitation signal for exciting a specimen having a nuclear quadrupole resonance, a signal sampling device for sampling a response signal received from the specimen to produce a plurality of samples, a data storage device for storing a plurality of data corresponding to said plurality of samples; and a processor for time coherently processing the plurality of data to sense the nuclear quadrupole resonance of said specimen. An optional second signal source for producing a probe signal directed at the specimen can also be used, where the response signal corresponds to the probe signal having reflected off the specimen.
