Abstract: A method for measuring body parameters includes irradiating a body area during a first time window using a first illumination source of a predetermined range of optical wavelengths and sampling, by a first plurality of spectral sensors, a first received light spectrum for the body area. The method continues by outputting, via one or more interfaces, information representative of the first received light spectrum during the first time window to a processor. The method continues by irradiating the body area during a second time window using a second illumination source of a predetermined range of optical wavelengths and sampling, by a second plurality of spectral sensors, a second received light spectrum for the body area. The method continues by outputting, via the one or more interfaces, information representative of the second received light spectrum during the first time window to the processor.
