4.用于准直光束很久以前就考虑了“波片堆”偏振仪的几何问题~([9,10])。Bird和Shurcliff考虑了AgCl“厚”波片堆,Conn和Eaton考虑了很薄(约3μm)的薄膜堆~[10],干涉效应占了主导作用。采用硅基片的偏振仪是一种由几百微米厚的宽间隙和波片构成
4. The problem of the geometry of the polarizer for the “stack” polarizer has long been considered for collimating the beam ~ ([9,10]). Bird and Shurcliff considered AgCl “thick” wave plate stacks, and Conn and Eaton considered thin (~ 3μm) film stacks ~ [10], with interference effects dominating. A polarizer using a silicon substrate is a wide gap and wave plate that is hundreds of microns thick
