anaberration
Examples
- In order to break through the choke point of the traditional design of a telephoto lens , how to eliminate aberrance by means of hybrid refraction - diffraction was studied from the view of the phase polynomial of diffractive surface and phase transformation polynomial of general lens
摘要为了突破长焦物镜传统设计中的局限性，从衍射面的相位多项式出发，结合一般透镜的相位变换式，对折衍混合消像差理论进行了探讨。 - A method used for designing a flat - field awg is also presented based on the mspm . in this design , the images of all the channels are on the same line . this greatly simplifies the structure of an awg and makes it much easier to integrate with other devices
在多点消像差方法的基础上，实现了平场型awg器件的设计，使得所有通道波长的成像位置都在同一条直线上，简化了器件的结构，有利于器件集成，使awg器件的设计更加灵活。 - In this thesis , a multiple - stigmatic - point method ( mspm ) is applied to improve the conventional rowland - type design , which is especially important for designing an awg when the total number of the channels is large . it greatly improves the performance of an awg , such as the channel uniformity , the crosstalk and the insertion loss
文中采用多点消像差方法，对多通道数awg器件的结构设计进行了改进，改善了传统的rowland圆结构设计中存在的缘通道的性能严重劣化的问题，大大改善了多通道数awg各通道性能的均匀性，改善了器件性能。
