Effects of Glucose Concentration on the SWIR Optical Properties of Whole Human Blood

Understanding how glucose concentration affects the optical properties of whole human blood in the Short-Wave Infrared (SWIR) range may be essential for improving glucose monitoring techniques. This technology would be highly beneficial to those with diabetes. We measured the optical properties of whole human blood across varying glucose concentrations using SWIR light and the Inverse Adding-Doubling (IAD) method. Our results showed a significant change in the blood's optical properties with increasing glucose concentration. These findings suggest that SWIR optical measurements could provide valuable insights for the development of improved optical glucose monitoring technologies.
