aspheric mirror
aspheric reflector
aspheric-mirror
aspherical mirror
Examples
- The machining approach is verified to be simple and reliable by computer simulation , so the production efficiency can be improved and the equipment input can be reduced
通过计算机模拟验证了该加工方法的简便与可靠性，可以降低非球面反射镜加工的设备投入，提高生产效率。 - Several test results of other , nff - axis aspheric mirrors are also given . all of the mirrors have accuracy better than 1 / 40x , and have fulfilled the demands by designer
实践证明，本文的研究适用于大口径离轴非球面反射镜的加工，有效地提高了非球面的加工效率和精度水平。 - This dissertation presents improved methods for both testing results analysis and aspheric mirrors fabrication concerning computer controlled optical surfacing ( ccos ) technology to improve its efficiency and accuracy . a new ccos model based on " relative tool path " is proposed , and a method is developed to solve and evaluate fabricating parameters
目前ccos ( computercontrolledopticalsurfacing )技术被广泛用于离轴非球面反射镜的制造，本文针对该技术中涉及到的一些问题开展较为深入的研究，以进一步提高离轴非球面的加工效率和精度。 - In this paper , we brought forward an innovative idea : according to the characteristics of easy deformation of ultra - thin mirror , we employ a sphere mirror , which is easier to fabricate and test , to replace the aspherical mirror , then the sphere mirror is deformed into an aspherical one by active optics technology . on this purpose , we need to study the mechanism and method of shaping a spherical mirror into an aspherical one
由于非球面镜的加工和检测都比较困难,因此本文提出了一个大胆的设想:利用超薄镜易于变形的特点,以加工和检测难度远低于非球面的球面来代替非球面,运用镜面的主动控制技术将球面反射镜变形成所需精度的非球面反射镜。 - The optical manufacturing for off - axis aspheric mirrors has become increasingly challenging for two reasons . the mirrors , in addition to being larger , are more aspheric and off - axis in order to meet the requirement of next generation space camera , which is commonly configured as three - mirror - anastigmat ( tma ) to get both wide fov and high resolution , and the required accuracy is more stringent
近年来，人们提出了“离轴三反消像散” ( tma )结构来满足下一代空间相机“详查”和“宽覆盖”的技术要求，该结构中要求使用三块离轴非球面反射镜，而大口径、高精度离轴非球面反射镜的制造技术是研制tma结构空间相机的主要技术瓶颈之一。
