摘要
在白光照射下,衍射光学透镜的焦距不仅同材料色散和波长色散有关,而且还同孔径因子有关。基于折射率随波长变化的经验公式,利用自编的仿真计算程序包,得到了透镜焦距、材料色散、波长色散、孔径因子之间的关系曲线。所获得的理论分析和仿真计算结果为进一步设计消色差的纯衍射目视光学系统提供了理论依据,具有一定的指导意义。
When the diffractive optical lens is illuminated by white light, its focal length not only relates to material dispersion and wavelength dispersion, but also to aperture factor. Based on the empirical formula of refractive index with the change of wavelength, the relation curves among the focal length of diffractive optical lens, material dispersion, wavelength dispersion and aperture factor are obtained by using the selfprogramming emulating package. The analytical and simulated results achieved provide the principal foundation and have an important meaning for designing achromatic onlydiffractive visual optical system.
