Abstract
The main feature of the compound diffractive telescope is the combination of diffractive optics with compound structure arranged eyepieces. In this paper, a design of the compound diffractive telescope is firstly introduced, and a 4.2° FOV is obtained with one primary lens and twenty-one eyepieces. Secondly, image characteristic of different channels is analyzed with the design wavelength in ASAP, and one modified phase function model of diffractive optical element is introduced to analyze the MTF curves for 0° FOV, which provides a more accurate prediction of the performance of the system. Then the system is tested by the star image test, and the diffraction limit images are got within ± 2° FOV. And finally, two pictures taken from the adjacent FOV proved to be able to be spliced together. All the results above demonstrate that a good performance of the compound diffractive telescope.
