The aim is to validate a non-invasive reflectance imaging system for measuring optical properties of biomedical tissues.
Constructed a spatially resolved reflectance imaging system.
Performed calibration procedures considering unique beam profiles.
Used Monte Carlo methods for quantitative comparisons of reflectance measurements.
Experimented with highly scattering sphere suspensions with varying absorption.
Recovered absorption measurements within 20% of reference values.
Achieved reduced scatter within 6% compared to integrating sphere measurements.
Validated the imaging system for future in vivo optical measurements of human skin.
