Abstract

We present on blood optical property alterations induced by lipids. Mie simulations were conducted to estimate the magnitude of μ_s^' changes due to changes in lipoprotein particles in blood after a meal. Longitudinal SFDI measurements were performed on the dorsal surface of volunteers’ hands pre and post high fat meal for 5 hours to monitor optical property changes within superficial vessels. The results show an increase in μ_s^' and a decrease in μ_a with higher changes observed in SFDI measurements compared to Mie simulations, potentially due to hemodynamic alterations that occur after a meal.
