You could check "Scan Type" setting under Field Curvature/Distortion curve to either scan across x or y direction. In addition, you could use Grid Distortion, which give you an overview of distortion. For coma, it normally displays as a parabolic curve in Ray Fan plot but it can be a bit complicated to analyse if you also have other dominating aberrations. Another way to look into coma is by looking at Zernike Standard Coefficeint, the term 5 and 6 correspond to coma in y and x orientation respectively. ZERN operands should help to extract these values. However, these are only for the third order. Once you go higher order aberrations, the conversion between Seidel and Zernike becomes not so stright forward. |

可以利用TRAX TRAY REAX REAY這幾個(gè)操作數(shù)根據(jù)像差的定義來(lái)描述像差(包括高階的像差),與transverse ray fan plot類(lèi)似。 |
