室内模拟遥感实验室装备的一套精心设计的系统,能够在这个大型暗室内模拟太阳光和入射角,照射自然状态下的地物,用6米直径的双向光度计在半球空间内测量地物的双向光谱反射比系数,为遥感图象的解译和传感器最佳波段的选择提供可靠的数据。一、原理概述和测量要求如图1所示,太阳模拟器1的平行光,被旋转反射镜2反射,以不同的天顶角照射
An elaborate system of indoor simulation telemetry lab equipment that simulates sunlight and angle of incidence in this large, dark room illuminates features in natural conditions and measures features in hemispherical space with a 6-meter diameter bi-directional photometer The bi-directional spectral reflectance coefficient provides reliable data for the interpretation of remote sensing images and the selection of the optimal wavelength band of the sensor. First, the principle of overview and measurement requirements As shown in Figure 1, the parallel light of the solar simulator 1 is reflected by the rotating mirror 2 to different zenith angles
