Abstract
A device capable of producing a high resolution chemical analysis of a sample, such as fluid, is based upon nuclear magnetic resonance (NMR) spectroscopy. The nuclear magnetic polarizations of the sample are generated by sequentially illuminating the sample with a focused beam of light carrying angular orbital angular momentum (OAM) and possibly momentum (spin). Unlike in a typical NMR used for magnetic nuclear resonance imaging (MRI) or spectroscopy, the present device does not make use of a strong magnet.
