Embodiment Construction

[0062]The invention comprises a noninvasive analyzer apparatus and method of use thereof comprising a near-infrared source, a detector, and a photon transport system configured to direct photons from the source to the detector via an analyzer-sample optical interface. The photon transport system includes a dynamically position light directing unit optionally used to, within a measurement time period for a single analyte concentration determination, change any of: radius, energy, intensity, position, incident angle, solid angle, and / or depth of penetration of photons entering skin of a subject.

[0063]In another embodiment, two optically stacked arrays of optical filters as a portion of a noninvasive analyzer apparatus are used. The stacked arrays of optical filters are optionally configured to pass multiple distinct and / or overlapping wavelength ranges to an array of detectors, where the filter combination—detector array distance resolves diffusely reflected / partially absorbed optical...

Abstract

A noninvasive analyzer apparatus and method of use thereof is described comprising a near-infrared source, a detector, and a photon transport system configured to direct photons from the source to the detector via an analyzer-sample optical interface. The photon transport system includes a dynamically position light directing unit used to, within a measurement time period for a single analyte concentration determination, change any of: radius, energy, intensity, position, incident angle, solid angle, and / or depth of penetration of a beam of photons entering skin of a subject.
