Paper Abstract
Polarimetric glucose sensing is a promising method for noninvasive estimation of blood glucose concentration.
Published methods of polarimetric glucose sensing generally rely on measuring the rotation of light as it traverses
the aqueous humor of the eye. In this article, an interferometer is described that can detect polarization changes
due to glucose without the use of polarization control or polarization analyzing elements. Without polarizers,
this system is sensitive to optical activity, inherent to glucose, but minimally sensitive to linear retardance,
inherent to the cornea. The underlying principle of the system was experimentally verified using spectral domain
optical coherence tomography. A detection scheme involving amplitude modulation was simulated, demonstrating
sensitivity to clinically relevant glucose concentrations and an acceptable error due to time varying linear
birefringence of the cornea using Clarke Error Grid Analysis.
