Abstract
In one aspect, the present invention provides systems and methods for non-invasively determining the amount of an analyte in a subject's blood using a set of light sources and a set of light detectors for measuring optical density. Advantageously, in embodiments of the invention, the light sources are operated such that each of the light sources outputs light at the same time, thereby concurrently illuminating the fingertip with light from each light source, and while the fingertip is illuminated by the light sources, a data processor reads data output from each light detector substantially simultaneously.
