| Abstract: | A seeker optical system of non-spherical dome with large fineness ratio is purposed in this paper.Properties of the aberration and its correction methods are analyzed and discussed.The designed dome optical system has the following features: fineness ratio is 2,operating waveband is the middle infrared spectrum,half of the field is 30 degrees,and its F number is 2.The results show that the image quality is approaching the diffraction limit and satisfies the requirements of imaging optical system. |
