摘要
处于并联态的几个等角倒锥嵌于腔体开口端,其间的细长狭缝几乎能耗尽腔体的入射光能,以此概念模拟黑体得ε=0.99999999的大口径黑体模拟器。
Several equal angle inverted cones in parallel are inserted into the opening end of cavity, among which the small long slits can almost deplete the incident light energy in the cavity. Using this concept, a blackbody simulator with e = 0.99999999 and large aperture can be obtained by simulating the backbody.
