With the development of optical systems to improve the detection accuracy of polarization aberration brings more and more problems, affecting the polarization detection accuracy of the system as well as the imaging contrast, so it is necessary to quantitatively analyze and calculate the polarization aberration. The polarization aberration distribution of a refractive anamorphic optical system is analyzed using a three-dimensional polarized light tracing method. Calculating the distribution of diattenuation and phase retardance for each face type yields a maximum diattenuation of 0.145 and a maximum phase retardance of 1.46x10-2rad both occurring in the second reflector. In addition the Jones pupil and amplitude response matrices of the system were calculated, ghost psf for this deformation optical imaging contrast was limited to the order of 10^-6.
