提出一种基于内反射原理的可变光学衰减器 ,这种利用一加长的棱镜和涂于棱镜上下两底面的SiO2 薄膜的简单结构 ,使随入射角变化的反射光实现弱偏振相关和大动态范围的衰减
A variable optical attenuator based on the principle of internal reflection is proposed. This simple structure using an elongated prism and a SiO2 film applied to the upper and lower prism faces makes polarization-dependent and large-dynamic Decay of the range
