Abstract

A nuclear quadrupole resonance system which senses the stimulated emission from target molecules includes in a calibration step and a stimulated emission response detection step, with the system employing clutter cancellation involving linear regression and the use of cross correlation with a series of known molecular signatures, both increasing the signal-to-noise ratio of the system.
