Method of an apparatus for nuclear quadrupole resonance testing a sample |
| abstract |
A method of nuclear quadrupole resonance testing a sample is disclosed in which thenexcitation applied to the sample is arranged so that phase and amplitude informationnmay be obtained from the response signal, and in which the signal is resolved intontwo components. Particularly if a parameter such as radio-frequency field strengthnvaries with position, this may give an indication of the distribution of nuclei in thensample, preferably from the phase of the response signal. Positional information cannalso be obtained by measunng from two or more reference points. This may benemployed in imaging. The phase information may be employed to improve the signalnto noise ratio obtainable in other methods where only amplitude information wasnpreviously available, for example in distinguishing genuine NQR response signalsnfrom spurious signals. |
