- Axicon's diffraction mode for spherical wave beam with eccentricity[J]. 引用该论文 王中宇;张朵;李萌;高晓颖.
- It is possible that the incident spherical wave beam is tilted with the optical axis of the axicon in practical measurement. 在实际使用中,入射球面波很可能与圆锥透镜的光轴发生倾斜。
- Using spherical wave beam to illuminate an axicon will result in a beam with small central spot and large focal depth, which is useful for laser communication and long-distance measurement. 由于球面波入射圆锥透镜所产生的出射光束具有焦深长和中心光斑直径较小的特点,适合激光通信以及长距离测量。
- A little apart from the surf ace, the longitudinal wave beam may exist and propagate parallel to the surface,yet has to connect with its corresponding gliding irrotational waves. 离开固体表面稍远的区域,可以有平行于表面传播的纵波声束存在,但是需要与相应的滑行集散波相互衔接。
