Abstract
A method and system for non-invasively measuring the concentration of an optically-active substance in a subject are provided. The system includes a light source adapted to transmit light towards a subject or object having a concentration of an optically-active substance, a polarizer positioned between the light source and the subject, an image capturing device, and a processor. The image capturing device is positioned to receive light reflected from the subject and create a measured image therefrom. The measured image defines measured light intensity data. The processor is configured to calculate a concentration of the optically-active substance based on a selected portion of the measured light intensity data.
