可变光衰减器 meaning in English

variable optical attenuator

Polymer - based variable optical attenuator
聚合物热光可变光衰减器
The temperature character of a novel variable optical attenuator
新型可变光衰减器的温度特性研究
Electro - optical curves for lc cells have been analyzed and it has been shown mat a large attenuation range and a shallow attenuation slope can be achieved simultaneously for a variable optical attenuator based on a parallel - aligned lc cell with an appropriate surface anchoring strength . as compared with the existing liquid crystal - based voa structure ( using two cascaded lc cells with a particular material ) , the present structure is simple and has no special requirement for the lc materials
提出了基于弱锚定平行排列液晶盒的可变光衰减器(衰减范围大、衰减曲线下降平缓以保证调节精度) ，与己有液晶型可变光衰减器结构(选用特定液晶材料、两个液晶盒级联结构)相比较，本论文提出的基于弱锚定平行排列液晶盒的可变光衰减器结构简单，同时对于液晶材料无特殊要求。
