Relationship between Human Glucose Level and Optical De/Polarization Information in 600 nm-800nm Wavelength Region

Patients have to check their blood glucose level at least four times a day. If regular measurement is not made, hypoglycemia and hyperglycemia occurrence possibility increases. When measurements are not made regularly it is preparing the ground for organ damage in long term and life risk in short term. Nowadays many people with diabetes need to measure blood glucose levels by drilling their fingers, squeezing blood droplets on test strips and treating the results with portable glucometers. This method seriously disrupts patient's comfort. So, there is a growing need for a new generation of glucose-level monitoring systems. For this reasons' this study focused on non-invasive methods based on optical de-polarization rate relation with glucose level. By using optics-photonics information modeled biological tissue (skin layers and blood) is illuminated by circularly polarized light, and elliptically polarized light at the other side of tissue (transmitted light) is obtained.
