The Potential Use of Polarized Reflected Light in the Remote Sensing of Soil Moisture
2006
Doll, Barry
Polarization of light reflected from soil and sand samples is studied as surface moisture and texture of the samples are varied. A reflectometer equipped with a rotating analyzer records the polarization percentage of the reflected light. The percentage of polarization runs from 15.5% for dry soil to 89% for saturated soil, indicating that the polarization method may be viable as a remote sensing system for determining soil moistures. Background on the methods and implications of the results are presented.
