NON-INVASIVE OCULAR MONITORING
First Claim
1. A device for measuring an analyte concentration level in a subject, the device comprising:
- a light source configured for illuminating at least a portion of an anterior region of an eye of the subject with incident light having a substantially broad illumination spectrum at an angle substantially tangential to the surface of the eye;
an optical collector configured for detecting reflected light from the at least a portion of the anterior region of the eye;
an analyzer configured for analyzing the detected reflected light; and
a processor configured to determine the analyte concentration level in the subject based on the analyzed reflected light.

15. A device for measuring an analyte concentration level in a subject, the device comprising:
-
a light source configured for illuminating at least a portion of an anterior region of an eye of the subject with incident light having a substantially broad illumination spectrum at an angle substantially tangential to the surface of the eye; an optical splitter configured for splitting the incident light into first polarized rays and second polarized rays, wherein a polarization of the first polarized rays is substantially perpendicular to a polarization of the second polarized rays; a first polarization rotation element configured for rotating the polarization of the first polarized rays to be substantially parallel to the polarization of the second polarized rays; a first variable rotator configured for rotating the polarization of the first polarized rays and the polarization of the second polarized rays; a second variable rotator configured for rotating a polarization of first reflected rays and a polarization of second reflected rays, wherein the first reflected rays and the second reflected rays are reflected from the at least a portion of the anterior region of eye; a second polarization rotation element configured for rotating the polarization of the second reflected rays to be substantially perpendicular to the polarization of the first reflected rays; an optical combiner configured for combining the first and second reflected rays into combined reflected rays; an optical collector configured for detecting the combined reflected rays; an analyzer configured for analyzing the combined reflected rays; and a processor configured to determine the analyte concentration level in the subject based on the analyzed combined reflected rays. - View Dependent Claims (16, 17, 18, 19, 20)
