Abstract
We report results of a study demonstrating that swept-source spectral interferometry and spectral phase analysis may be applied to determine quantitatively the concentration of glucose in aqueous solutions. The optical system incorporates a frequency swept laser and fiber-based common-path interferometer and provides a compact, stable experimental system. Spectral phase analysis includes a fast Lomb-Scargle algorithm and a multitaper spectral estimation method that allows for time-frequency analysis. The results show highly sensitive and accurate determination of glucose concentration in solutions with 0.54 mM of resolution and 0.999 correlation coefficient. Swept-source spectral interferometry with spectral phase analysis is a promising methodology for further development of a convenient glucose-sensing method with superior sensitive and accuracy.
