Abstract

With the quantitative remote sensing developing, the promising use of multi-angle polarization information has been recognized. Since polarized reflectance always goes with bidirectional reflectance, we can attain the polarized three-dimensional spatial distribution of the target by a polarizer while detecting its bidirectional reflectance. In this paper, polarized reflectance of dry peat with different water content was collected using a polarized bi-directional reflectance photometer. The polarized measurements for peat samples with different water content were performed at various zenith viewing angles, incidence light zenith angles and azimuth angles with band A (630-690nm) and band B(760-1100nm). The polarization changes of different peat moisture were analyzed quantitatively. The results revealed that there were close and positive relationship between peat polarized reflectance characteristics and water content, peat characteristics and sensor's viewing geometry. Polarized reflectance of peat will not only help to find a new way for peat detection remotely, but also provide a theoretical basis for further research on the polarized light remote sensing.
