摘要
通过实验研究了在强背景光、反向散射条件下,十余种建筑物墙面靶材料在波长λ=1.55 μm下的反射特性.利用调制光谱技术,通过与标准反射参考板的比对测量,得到了这几种墙面靶材料的双向反射分布函数.其结果为设计气体遥感探测仪器信号放大器的动态范围、测试距离以及理论计算最低探测灵敏度提供了必要的实验依据.
Abstract
In this article, the characteristics of several surface materials of wall as target for laser remote detection of toxic and hazardous gases were described. The backscatter data were obtained by a novel measured method with one particular technique. By use of these data, the bidirectional reflectance distribution function (BRDF) of these surface materials was calculated by comparing with that of the PTFE diffuse plate.
