Abstract
Embodiments of the invention relate to an apparatus including a light source to generate a plurality of light beams with each of the plurality of light beams having a different wavelength range. The apparatus also includes a light funnel to direct the plurality of light beams to the target area, an aperture to direct the plurality of light beams emitting from the target area to a lens, the lens configured to collect the light beams emitting from the target area. Further, the apparatus includes a detector including a plurality of light-sensing devices each configured to detect a light beam and configured to generate an output signal indicative of an intensity of light detected and a processor for determining the blood characteristic as a function of each generated output signal.
