研究了90°离轴抛物面反射镜的固有像差。研究了OAPM准直和聚焦THz辐射的不同组合所产生的像差。结果发现，与父抛物线重合的轴的安排有一个最小的几何光斑的混乱。
The inherent aberrations of 90° off-axis parabolic mirrors (OAPMs) are investigated. The resulting aberrations of different combinations of OAPMs for collimating and focusing the THz radiation are investigated. It is found that the arrangement with coinciding axes of the parent parabolas has a minimal geometrical optical spot of confusion.
