摘要	In order to achieve high spatial resolution polarization interferometry in the infrared wave band, a novel polarization interference imaging system based on micro-static interference systems is proposed in this paper. The system does not contain slits and has the advantage of having a large luminous flux. This paper introduces the principles of a linear polarization interference imaging system, calculates its initial structure parameters by using the Paraxial optics theory and optimizes the system's design. When the incident light is completely non-polarized and polarized, the transmission rate of the system is analyzed and the minimum weak radiation detected by the system is obtained. In order to further improve the system's performance and reduce the effect of random fluctuations in detector intensity on polarization measurements, the polarization measurement matrix of the system is optimized by using equal weight variance and the correctness of the method is verified by numerical simulation. Finally, the influence of the Polarizer's rotation error on the polarization measurement is analyzed, and the tolerance of polarizer is given in order to satisfy the polarization detection accuracy of 2%. The design results show that the imaging quality of the Fourier transform line polarization interference imaging system is good and that the modulation transfer function value of each field is greater than 0.6 in the characteristic frequency 17 lp/mm of the detector, which meets the usage requirements of the system. 2019, China Science Publishing & Media LTD.
