A laser-source bidirectional reflectometer that is fully automated and has angular resolution on the order of one degree has been designed and built. The direction of incidence and viewing can be independently varied over an entire hemisphere except for directions more than 77.5° from the normal, and the two directions must be at least 2.5° apart. Bidirectional reflectances for 15 samples of black and white coatings are presented.
设计并制造了一种完全自动化的激光源双向反射仪,其角分辨率约为1度。除了与法线方向夹角超过77.5°的方向外,入射方向和观测方向可以在整个半球范围内独立变化,且这两个方向必须至少相距2.5°。文中给出了15种黑白涂层样品的双向反射率。
