Abstract
An embodiment relates generally to an improved method and apparatus for modulating the amplitude and rotation of the plane of polarization of linearly polarized light for multiple uses but primarily as part of a noninvasive glucose monitoring system. As compared to previous monitoring systems, an embodiment provides faster monitoring while maintaining or even reducing noise and minimizing system complexity. Embodiments described herein address these concerns with a modulation and compensation approach that both uses a single high speed device and also modulation of the lasers.
