介绍一种二元光学元件的设计方法.为了克服达曼光栅在二维设计上的局限性,采取均匀采样的矩形孔径编码方式进行优化设计.结果表明:与达曼光栅相比,不仅可将总衍射效率提高10%以上,还可得到更多样的二维设计图样,只是输出点阵均匀度略低于达曼光栅.因此,在均匀度要求不太高的高强光束变换中,这种二值型位相光栅的设计方法对于设计二维衍射图样十分简便有效,且其计算结果易于加工制作,具有很高的应用价值. |

A kind of design lor binary optics element(BOB) is introduced.The even sampling coding schemes fur pixellated grating method is adopted in optimizing design to overcome then disadvantage of Dammann grating in design 21) output patterns. The results indicate that, compared with the Dammann grating, the pixellated grating not only increase the diffrartive efficiency mcire lluui 10% , hut also be more adaptive in getting the diversiform of two - dimensional patterns. But the intensity distribution in output spots by pixellated grating is little worse than by Dammtinn grating. So for the transformation of high - power laser beam which demands in the uniformity is not very highi Ihis kind of design lor BOK is very convenient in 21) patterns design. And the calculated reside is very easy In make tSie. HOE.So the applied value is very high. |
