Polarized Bidirectional Reflectance Spectra of Polished Granite
The granite is widely used for city architectural decoration, outdoor sculpture. Study on granite reflection is important for artificial building recognition and rock or mineral exploration. The Bidirectional Reflectance Distribution Function (BRDF) is used in conventional remote sensing to characterize the geometrical scatter of materials. Polarization occurs with multi-angle scatter. 90°and 0°polarized bidirectional reflection along the waveband of 300~2500nm for various view azimuth and zenith angles on polished granite are acquired. DOP then is calculated.
