Study on multiangular reflectance polarization characteristics of mineral in visible light waveband
摘要
Abstract
In order to research multiangular reflectance polarization characteristics of minerals, the reflectance polarization spectrum of minerals in visible light waveband was measured by the method of changing the incident angle and detection angle. After theory analysis and experimental verification, the results show that the degree of polarization ( DOP) of minerals is less affected by wavelength in visible light region, and DOP is stable. Incident angle and detection angle have significant influence on polarization spectrum. With the increase of incident angle and detection angle, DOP firstly increases and then decreases. The maximum angle is nearing Brewster angle. DOP of minerals have great differences when incident angle and detection angle vary between 55°and 65°. DOP of chalcedony is significantly higher than the other three minerals. DOP of chalcedony with smaller particles and higher crystallinity is the highest and DOP of opal with amorphous structure is the smallest. The study is feasible and reliable to identify and classify minerals by the degree of polarization and provides new way for minerals detection.关键词
