Claim 4:
5. An apparatus for use in a noninvasive determination of an analyte property of a person having skin, comprising:
a noninvasive analyzer comprising:
a sample probe head, said sample probe head comprising a sample side surface;
a set of sources at least partially embedded in said sample probe head, each source of said set of sources optically coupled to a corresponding illumination zone of a set of illumination zones on said sample side surface;
a set of detectors at least partially embedded in said sample probe head, each detector of said set of detectors optically coupled to a corresponding detection zone of a set of detection zones on said sample side surface, wherein a first set of at least two illumination zones of said set of illumination zones and a first set of at least three detection zones of said set of detection zones intersect on a first line;
a first diode source, configured to emit a first mean wavelength in a range of 1300 to 1490 nm, optically coupled to a first illumination zone on said first line, wherein a center point of said first illumination zone is at a first radial distance from a longitudinal center point of said at least three detection zones;
a second diode source, configured to emit a second mean wavelength in a range of 1300 to 1490 nm, optically coupled to a second illumination zone on said first line, wherein a center point of said second illumination zone is at a second radial distance from said longitudinal center point of said at least three detection zones, said second radial distance being at least one-half millimeter longer than said first radial distance; and
a transducer configured to vibrate the skin of the person during use, said transducer being mechanically coupled to said sample probe head.
