A method for determining analyte concentration levels is provided. The
method includes acquiring radiation scattered off or transmitted by a
target, analyzing at least a first portion of the radiation via a first
technique to generate a first measurement of analyte concentration
levels, and analyzing at least a second portion of the radiation via a
second technique to generate a second measurement of analyte
concentration levels. The method further determines analyte concentration
levels based on at least one of the first measurement or the second
measurement. In addition, a system for implementing the method and a
probe for measuring and monitoring the analyte concentration levels is
provided.
