我们描述了一种成像散射仪，允许半球反射率测量作为入射角的函数。散射仪的核心是一个椭圆反射镜，它将半球形反射压缩成可以由普通光学系统成像的锥形光束。该仪器的性能是通过测量的蓝虹彩背翅鳞片的nymphalid Morpho aega和哑光绿色腹侧翅鳞片的lycaenid Callophrys鲁比的散射剖面。(C)2008年美国光学学会
We describe an imaging scatterometer allowing hemispherical reflectance measurements as a function of the angle of incidence. The heart of the scatterometer is an ellipsoidal reflector, which compresses the hemispherical reflection into a cone-shaped beam that can be imaged by a normal optical system. The instrument's performance is illustrated by measurements of the scattering profiles of the blue-iridescent dorsal wing scales of the nymphalid Morpho aega and the matte-green ventral wing scales of the lycaenid Callophrys rubi.
