Abstract

We present a technique for visualizing subsurface water content of leaves and human skin using dual-band polarization imaging and a multimedia projector as light source. The multimedia projector provides control over the intensity, pattern and frequency of the light source. Polarization imaging ensures that the subsurface of the skin is the layer being analyzed. However, this method failed for the leaf. This proposed technique may replace the time consuming techniques of leaf water content estimation and an alternative to skin moisture tests that depend on electrical conductance which may be erroneous due to the electrolytes present in the epidermis.
