Design and analysis of the Galileo-type Monocentric multiscale system
摘要
Abstract
Monocentric multiscale systems offer the advantages of miniaturization and a large field of view.In order to further realize the miniaturization and light weight of the large field-of-view system,we adopt the Galileo-type monocentric multiscale system form and design a monocentric multiscale system operating in the visible spectrum.The modulation transfer function of the system is greater than 0.3 at a frequency of 208 lp/mm,the root-mean-square radius of the full-field diffuse spot is smaller than the detector pixel size of 2.4 μm,and the imaging quality is close to the diffraction limit.The monocentric multiscale system structure has a couple of special characteristics:the relay lenses are closely arranged and the crosstalk stray light between the relay lenses seriously affects the imaging quality.To solve the problem,we apply the method of suppressing the crosstalk stray light with the built-in stary light stop.On the basis,we carry out the simula-tion and analysis of the stray light of the optical system.Analysis results show that the stray light coefficients are all reduced to less than 1×10-6 after the addition of the stray light stop,which verifies the crosstalk stray light suppression method.关键词
