Abstract
Systems and methods for pre-tuning a main Nuclear Quadrupole Resonance (NQR) probe using a forward sensing probe include a determination of an amount of resonance detuning of the forward sensing probe caused by a moving object entering a field of view of the forward sensing probe. The amount of resonance detuning is used to pre-tune the main probe such that when the moving object enters a field of view of the main probe, the main probe will move back into tune while delivering optimal power to the object for measurement and identification of a material therein.
Claims21
A method of nuclear quadrupole resonance (NQR) measurement of an object, comprising:
- detecting an object as it enters a field of view of a forward sensing resonance probe (FSP);
- determining an amount of resonance detuning of the FSP caused by the detected object;
- and
- pre-tuning a main NQR probe (MP) based on the amount of detuning of the FSP.
A nuclear quadrupole resonance (NQR) measuring system, comprising:
- a forward sensing resonance probe (FSP);
- a main NQR probe (MP);
- and
- a tuner coupled to each of the forward sensing resonance probe and the main NQR probe;
- wherein the FSP is configured to detect an object as it enters a field of view of the FSP and to measure the object and determine an amount of resonance detuning of the FSP caused by the detected object;
- and
- wherein the tuner is configured to pre-tune the MP based on the determined amount of resonance detuning of the FSP.
