自聚焦透镜的有效半径和有效数值孔径

Effective Radius and Effective Numerical Aperture of the Self—Focusing Lens Array

研究自聚焦透镜的有效半径和有效数值孔径,得到了物距和数值孔径间的关系并计算了物距、数值孔径和分辩率,可作为自聚焦透镜列阵中透镜长度选择的依据之一。

We discussed the effective radius and effective numerical aperture of selfoc lens; the rela- tionship between object distance and numerical aperture is obtained. We also calculated the object distance, numerical aperture and resolution and use them as an important criterion to choose the length of arrays.
