Summary We examined techniques for non-invasive measurement of water content of skin by using diffuse reflectance near-infrared (800nm-1600nm) spectrophotometry. An in-vitro phantom with optical properties that mimic those of a wide range of soft tissues, but with a composition that can be altered in a controlled manner, was developed to test several different algorithms. The standard error of estimation of absolute water content from a four-wavelength linear regression, was found to be <±2%. The experimental results suggest that our approach can be used for assessment of acute dehydration.
