The Application of Monte Carlo Method in the Design of Probe of Non-invasive measurement of Blood Glucose

摘要

It is critical to improve the diffuse reflecting light energy for monitoring the blood glucose level from the skin spectra. The optic fiber probe used in non-invasive detection of blood glucose is consisted of one central fiber around with several optic fibers arranged in circle. The distance between central fiber and circle fibers d and the incidence angle β of the central fiber mainly determine the diffuse reflecting light energy. A three-layered skin model and Monte Carlo simulation algorithm are described to simulate the light propagation and distribution in the skin tissue. Simulation results showrf should be greater than 0.05cm and less than 0.1cm, and β should be less than 18°. The simulation results can be used in the probe design.
