Paper Abstract

High-resolution optical low-coherence reflectometry is applied to monitor biological samples. It has been found that the reflectivity of aged cow's milk is significantly lower than that of the fresh milk with a difference of 5.35dB. During the process of heating the fresh milk at a constant temperature of 80°C, the reflectivity of the milk gradually decreases with the increase of the heating duration. The technique is proved to be effective in monitoring the change in the refractive index of the sample.
