Embodiment Construction

[0045] In the following description, some non-limiting exemplary embodiments of the present invention for performing high resolution sample analysis will be described in more detail. Also, corresponding devices will be described by using exemplary block diagrams. It should be noted that these are exemplary embodiments only, but that many variations are possible as will become apparent to those skilled in the art upon reading the following description.

[0046] The invention is based on the fact that the OAM of the absorbed photon is transferred to the interacting molecule (conservation of angular momentum) and as a result:

[0047] - the electronic state reaches a saturated spin state;

[0048] - the angular momentum of the molecule (around the molecule's center of mass) is increased and oriented along the axis of propagation of the incident light; and

[0049] - All magnetic magnon precession motions associated with molecules (including electrons and nuclei) are oriented al...

Abstract

The present invention relates to a device capable of producing a high resolution chemical analysis of asample, such as fluid, based uponnuclear magneticresonance (NMR) spectroscopy, where the nuclear magnetic polarizations of the sample are generated by sequentiallyilluminating the sample with a focused beam of lightcarrying angular orbital angular momentum(OAM) and possiblymomentum (spin). Unlike in usual NMR used for (10) magneticnuclear resonance imaging (MRI) or spectroscopy, the invention does not make use of a strong magnet.

Description

technical field [0001] The present invention relates to a sample analysis method based on nuclear magnetic resonance (NMR) spectroscopy. The invention also relates to corresponding computer program products and devices for carrying out the method. Background technique [0002] NMR is usually performed in devices based on highly homogenous static magnetic fields with spatial variations of less than 1 ppm, resulting in nuclear spin processing at corresponding narrow frequency bands. However, this device is disadvantaged by the need to employ strong and homogeneous magnets, radio frequency (RF), and gradient coils that typically surround the sample being examined (such as a blood sample or tissue biopsy) and the relative complexity of such systems and high cost factors. [0003] NMR has found applications in magnetic resonance imaging (MRI) (since its sensitivity to the chemical properties of tissue constituents makes it the modality of choice for tissue characterization and ...
