摘要
本文应用标量衍射理论分析了色散对三维共焦成像系统超分辨的影响 .数值计算了圆形透镜的色散 ,结果表明 :焦斑的半径和焦深随入射波长的变大而减小 ,光斑的强度随入射波长的变大而增强 .与衍射效应产生的色散相比 ,透镜本身的折射率色散很小 .
The effects of dispersion on the super-resolution of 3-D confocal imaging system are analyzed by using the theory of scalar diffraction. The results of computer simulation show that both the radius of disk and the depth of focal length decrease as increasing incidence wavelength, meanwhile, the intensity of disk is enhanced. The dispersion caused from the chromatic aberrations of lens is smaller than that from diffraction effects of it.
