MULTIPLEXED PATHLENGTH RESOLVED NONINVASIVE ANALYZER APPARATUS WITH STACKED FILTERS AND METHOD OF USE THEREOF

摘要

A noninvasive analyzer apparatus and method of use thereof is described using a plurality of sample illumination zones optically coupled to at least two optically stacked two-dimensional optical filter arrays. Sectioned pixels and/or zones of a detector array are optionally filtered for different light throughput and/or are passed through various pathlengths using the stacked two-dimensional optical filter arrays. Resulting pathlength resolved/wavelength controlled groups of spectra are subsequently analyzed to determine an analyte property.

1. An apparatus for noninvasive analyte property estimation of a constituent of a human subject, comprising:
a near-infrared analyzer, comprising:
a near-infrared source;a detector array;a photon transport system configured to transport photons along an optical train from said near-infrared source to said detector array via an analyzer-subject interface;a first planar two-dimensional filter array comprising a first set of optical filters, said first set of optical filters comprising at least two optical filters; anda second planar two-dimensional filter array comprising a second set of optical filters,said optical train sequentially passing through said first planar two-dimensional filter array and said second planar two-dimensional filter array,said first planar two-dimensional filter array substantially parallel to said second planar two-dimensional filter array.
