Abstract
A device for measuring the polarization of a hyperpolarized resonant substance; in a particular embodiment a hyperpolarized noble gas. A specimen of the hyperpolarized substance is made one component of a coupled oscillator, the other component being a resonant electric circuit. Such a coupled system has, in general, two stable modes of oscillation, and their frequencies are related to various parameters of the system, including the polarization of the specimen of hyperpolarized substance. The polarization can therefore be deduced from these frequencies.
