Abstract
Some embodiments relate to a method of collecting light reflected from a subject and analyzing the light to monitor time-varying physiological parameters of the subject. Other embodiments relate to a system including collection optics to receive light reflected from a subject, filters to filter the light around a number of wavelengths, image capture zones to receive filtered light from the filters and to generate data to represent the filtered light and an image and signal processing system to monitor time-varying physiological parameters of the subject indicated by the data.
