| 摘 要： | 为了在野外准确地测量地表的双向反射系数(BRF),在这里介绍了由角度测量装置、ASD光谱仪组成的对地光谱测量系统。测量装置的探测方向可以在同一平面内以天顶方向为起点±90°旋转,精度为1.5°,同时可以在0.2～1.5m之间调节测量高度。在探头方向固定ASD地物光谱仪光纤,可以通过改变探测管调节实际测量视场角,使测量时视场角范围变化在8°～25°。该测量系统可以测量地表目标样品的直径范围为5～50cm。同时,通过在探头方向增加的偏振装置可以实现对地表的偏振测量。 |

| Abstract: | For obtaining accurate measurement of the bidirectional reflectance factor of land surface in field,we introduce a system which consists of ASD spectrometer and goniometer.The direction of the probe of the spectrometer can be changed between +90°and-90°,which bases on the zenith is the normal,the precision is 1.5°.The height can be adjusted from 0.2 to 1.5m.The measurement field of view can be changed from 8°to 25°.The measurement systemcan measure the surface in a diameter of 5～50cm.Meanwhile,the polarization measurement maybe realized by a polarized systemin front ofthe viewing direction. |
