A Norwegian University of Science and Technology Study
“In the experimental part of the study, we recorded HSI of facial skin. In total, 11 volunteers with Caucasian skin type were involved in the study, 8 males and 3 females. Their age was between 25 and 61 with mean age of 46. Blood cholesterol levels of the volunteers were between 125–285 mg/dl with mean value 217 mg/dl, including all three cholesterol level classes: normal, borderline and high blood cholesterol levels. Room temperature was controlled and ranged 24-26.5 °C.”
“The imaging was performed by a liquid crystal tunable filter system (VariSpec™ by Cambridge Research & Instrumentation, Inc.). The spectral range was 400 – 720 nm at a step size 10 nm. The light source was a white–LED light source (R130 by Smart Vision Lights, Inc.). Images were taken from a close distance, resulting in an image containing only eyes and skin around eyes.”
