摘要： Nuclear quadrupole resonance substance detection at a distance is provided by crossed or overlapping high frequency beams in which the frequency of one of the beams is offset with respect to the frequency of the other beam by an amount equal to the resonant frequency of the non-linear material to be detected. The presence of energy at the offset frequency within the overlapping beams pumps any non-linear material within the overlapping beams to cause stimulated emission which is detected, in one embodiment, utilizing a network analyzer, along with correlation of the detected stimulated emission signature with a library of signatures for predetermined substances.

摘要： A transmission line array is used for explosive/contraband detection using nuclear quadrupole resonance in which the array is driven in-phase with synchrony frequency-swept signals. Each of the balanced transmission lines is fed with a low power swept frequency source and stimulated emissions are picked out with a directional coupler. Location is provided using a cross grid array or a phase detector is used for each balanced line, with phase determining the distance to the sensed substance.

摘要： Rather than using balanced transmission lines the stimulated response due to nuclear quadrupole resonance can be detected using a single monopole, with multiple monopoles improving substance detection.
