Measurement device for non-invasively determining the concentration of polarising substances

摘要: A measurement device for non-invasively determining the concentration of polarising substances in human body, particular measuring sugar blood, has a light source (3), periodically rotating polariser/analyser (6, 4) linked to an angle sensor (3) rotation frequency polariser (6), and detector (1), as well electronic assembly (8) blood from measured values. The (6) converts polarisation into phase intensity curve transmitted light. may be determined by shift through object (5) with respect reference phase, static extinction (tissues blood) dynamic (only pulsating part blood). transmission or diffraction measurement. With only one system this is ccapable carrying out two independent measurements (phase modulation measurement). As freely selected, noise interferences affecting evaluation suppressed maximum extent.
