Abstract

Optical manufacturing technology, which features ultra-precision processing and measurement technology, has played a major role in promoting the development of cutting-edge technologies such as space gravitational wave detection, space high-resolution imaging optics, ground-based space target detection and recognition, inertial confinement fusion and extreme ultraviolet lithography. It is also of great importance in the development of high-end precision equipment. At present, the most challenging ultra-precision optical components include large aperture aspherical mirrors applied to large space optical telescopes and ultra-precision freeform mirrors for EUV lithography. This talk will introduce the current R&D results in manufacturing and measurement of large aperture space telescope mirrors and EUV lithography optics.

以超精密加工与测量技术为特征的光学制造技术，在推动空间引力波探测、空间高分辨率成像光学、地基空间目标检测与识别、惯性约束聚变、极紫外光刻等前沿技术发展方面发挥了重要作用，并且在高端精密设备的发展中也具有重要意义。目前最具挑战性的超精密光学元件包括应用于大型空间光学望远镜的高精度大口径非球面反射镜和用于极紫外光刻的超精密自由曲面反射镜。本次报告将介绍当前在大口径空间反射镜和EUV光刻光学器件的制造和测量方面的最新研究成果。

Biography

Xuejun Zhang received his Ph.D degree from Changchun Institute of Optics and Fine Mechanics (CIOMP) in 1997. He is now Deputy Director and Chief Engineer of CIOMP, also director, researcher, and doctoral supervisor at the Key Laboratory of Advanced Manufacturing Technology for Optical Systems of the Chinese Academy of Sciences. Dr. Zhang has been engaged in optical system design, manufacturing and testing for more than 20 years, and led his team in achieving a major breakthrough in the high-precision manufacturing technology of 4.03 meter-caliber SiC mirrors. The overall results are of world-leading level. He is also the team leader of the 30 Meter Telescope (TMT) Tertiary Mirror Manufacturing project. As principle investigator, he has completed a number of national research projects and won five National Awards for Achievements in Science and Technology. He was supported and rewarded by the National "Outstanding Youth" Fund, the Qian Xuesen Outstanding Contribution Award of the China Aerospace Foundation, and the Science and Technology Award of the Chinese Society for Space Science. Dr. Zhang is Fellow of SPIE and member of OSA and has published 161 peer reviewed papers.
