Abstract

Diffuse scattering measurements to determine the changes of glucose concentration in a highly scattering medium are conducted by using an optical heterodyne technique. The heterodyne technique can increase the signal-to-noise ratio (SNR) of the detection amplitude and phase by coherence gating and narrow detection bandwidth. The experimental results showed that a good sensitivity of 0.1% scattering change per mM is observed.
