First Claim
Patent Images
1. An apparatus for noninvasive determination of an analyte property of a tissue sample, comprising:
- a targeting system, wherein said targeting system generates a first signal;
a measuring system, wherein said measuring system generates a second signal optically representative of the tissue;
a controller, wherein said first signal from said targeting system is used by said controller during positioning of said measuring system relative to the tissue sample; and
a data processing module, wherein said module generates said analyte property using said second signal.
