Study On Complicated Pupil And Piston Error For The Golay6Configuration

The space optical system of high resolution is necessary for getting more information.High resolution can be obtained by an optical system with a large aperture and a long focuslength. But the traditional large-aperture optical system is limited by the manufacturingtechnology, cost and transportation. People have begun to seek new approaches to resolvethe problems. The complicated pupil optical imaging system is one of the approaches forthe realization of the large-aperture of high resolution.The issue studied in this dissertation is put forward. The research status, thesignificance of the complicated pupil optical imaging systems, the classification of thecomplicated pupil optical imaging systems, important parameters and the feature of Golay6configuration are introduced. The formulas of the pupil function and point spread function(PSF) of the Golay6complicated pupil are revealed about non-redundant Golay6configuration. Based on the pupil function and the PSF, the object image is simulated bythe Matlab. To improve the Contrast Ratio of the image of Golay-6complicated pupilsystem, the fractional differential operator is used to enhance the images. Based on theimaging principle of the complicated pupil, the feature of the complicated pupil for theGolay6configuration is analyzed, a complicated pupil telescope for the Golay6configuration is designed. The primary mirror of this telescope is replaced by the Golay-6complicated pupil and this system is designed by Zemax. The Modulation TransferFunction and the spot diagram of the system are analyzed. The sillicon correcting lensesare inserted to improve the field of the system and the quality of imaging.The influence which comes from piston error for the Golay6complicated apertureoptical system is studied by calculating and simulating the pupil function, point spread function and modulation transfer function. According to Strehl requirements, the pistonerror tolerance under the different radius and different fill factor is given and imagingsimulation is done by the Matlab.At last, the contents in this dissertation are summarized, and the further work isprospected.
