The application of Monte Carlo method in the design of probe of non-invasive measurement of blood glucose - art. no. 60401S

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 beta 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 show d should be greater than 0.05cm and less than 0.1cm, and beta should be less than 18 degrees. The simulation results can be used in the probe design.
