| 英文摘要 | In order to identify the target with little temperature difference in complicated and disguised infrared background, a decentered aperture-divided polarization imaging system is introduced in this paper. The design of decentered aperture-divided imaging system and relay imaging system adopted in decentered aperture-divided polarization imaging system are also studied. Firstly, the working theory and optical structure of the system are introduced according to the Stokes vectors. Secondly, the parameters of the optical system such as the eccentricity are calculated under the requirements of the structural parameters of the existing detectors in the laboratory, and silicon and germanium are selected as the lens materials. According to these parameters, both the structure of aperture-divided imaging system and that of relay imaging system are determined on this basis. Then the off-axis eccentric multi-structure design method is used to optimize the initial structure. The transformation method from ordinary infrared objective to image-side telecentric structure with real entrance pupil is studied. Finally, the overall system matching of aperture-divided imaging system and relay imaging system is completed. The results show that the overall system modulation transfer function(MTF) at Nyquist frequency of the detector of 17 lp/mm is greater than 0.6, which can meet the system design requirements. The structure introduced in this paper can detect the real-time polarization of the target, and possesses the advantages of compact structure. 2018, China Science Publishing & Media LTD.
