Influence and Correction of Wavefront Primary Aberrations for Radio Telescopes using Aberration Theory
《Research in Astronomy and Astrophysics》2023年第2期187-196,共10页Bin-bin Xiang Wei Wang You Ban Shang-min Lin Zhi-gang Wen Da-lin He Ming-hui Cai 
supported by the National Natural Science Foundation of China(NSFC,Grant No.U1931137);the National Key Basic Research Program of China(2018YFA0404702)。
Dual-reflector antennas are widely used in astronomical observations and satellite communication.Structural deformations of the reflectors for radio telescopes are inevitable in outside working conditions due to exter...

Optical–digital joint design of refractive telescope using chromatic priors被引量：2
《Chinese Optics Letters》2019年第5期68-71,共4页Jingang Zhang Yunfeng Nie Qiang Fu Yifan Peng 
supported by the Joint Foundation Program of the Chinese Academy of Sciences for Equipment Pre-Feasibility Study(No.6141A01011601);the National Natural Science Foundation of China(Nos.61775219 and61640422);the Equipment Research Program of the Chinese Academy of Sciences(No.Y70X25A1HY)
The conventional optical system design employs combinations of different lenses to combat aberrations, which usually leads to considerable volume and weight. In this Letter, a tailored design scheme that exploits stat...

Study on the design and Zernike aberrations of a segmented mirror telescope
《Chinese Physics B》2009年第7期2774-2778,共5页姜震宇 李林 黄一帆 
Project supported by the National High Technology Research and Development Program of China (Grant No 2006AA01Z339)
The segmented mirror telescope is widely used.The aberrations of segmented mirror systems are different from single mirror systems.This paper uses the Fourier optics theory to analyse the Zernike aberrations of segmen...

Design of apochromatic telescope without anomalous dispersion glasses被引量：1
《Chinese Optics Letters》2008年第2期146-148,共3页杨庆华 赵葆常 周仁魁 
A novel lens system with correction of secondary spectrum without using anomalous glasses is presented. The lens system comprises four separated lens components, with three of them being subapertures. Two examples of ...
