Abstract
A portable optical system includes interrogation of an implanted sensor located in a body tissue. The sensor contains a labeled analogue and a reference, which emit light at different wavelengths. The external optical instrument detects and discriminates between light from the labeled analogue and light from the reference. Logic in the detector receives and processes signals from the detector and generates an indication of the detected analyte level.
