The Theoretical Study Of The Optical Technology Of The Engineerization Of The Interference Imaging Spectrometer Of The CE-1 Satellite

This dissertation introduced the study work of my Ph. D. period, the main content in which discussed as follow:In the aspect of the wide band lens design, after studied the method of correcting the color aberration and the secondary spectrum at the visual lens by the former, the method of calculating the glass's P and V of the wide band were brought forward. Then by using of the pair of glasses which reduce the secondary spectrum, and solved by the equations of correcting the secondary spectrum, a lens which band is 420nm~900nm, focal length=450, F/5, field of view is 2.6° were designed. Its secondary spectrum error less than 0.05mm and the MTF nearly reached the limit of diffraction.In the interference imaging spectrometer, the FT lens was paid more attention in its manufacturing; assembling and material selecting. Any smaller variety in the refraction of the glasses to different wavelength from the theoretic value, then a large effect would be carried out. Therefore, the effects of the variety of the refraction to secondary were brought forward and the relationship between them was deduced. This formula was used into the CE-1 FT lens and gets a good result.Based on equivalent theoretic working map of the model of the lateral shear interferometer and the FT lens which used in the interference imaging spectrometer, the formula which expresses the relationship between the rays' angle aberration of the FT lens and the spectral resolution firstly was deduced. This formula were used into the CE-1 interference imaging spectrometer in order to evaluated the FT lens, by optical software Zemax test the rays' angle aberration of the FT lens, it was identified that the FT lens meet the requirement of the formula.By contrasting and calculating the two rays paths of the unwrapped map of the interferometer, the formula of the angle tolerance of the interferometer which related to the spectral resolution was firstly deduced. It was used in the CE-1 interferometer's angle tolerance analyzing. If there no other factor to be considering, the angle tolerance of the CE-1 interferometer should be conrol in the range of ±5" in the...
