In the context of exoplanet direct detection and characterization, where high-contrast imaging is mandatory, we present fully optimized two-dimensional pupil apodizations for which no specific geometric constraints are put on the pupil plane apodization, apart from the shape of the aperture itself. Masks for circular and segmented apertures are displayed, with and without a central obstruction and spiders. We can now optimize apodizers for any aperture shape, and examples of optimal masks are shown for the Subaru telescope, the Space Infrared telescope for Cosmology and Astrophysics (SPICA) and the James Webb Space Telescope (JWST). Several high-contrast regions are considered with different sizes, positions, shapes and contrasts. It is interesting to note that all the masks that result from these optimizations tend to have a binary transmission profile.
在系外行星直接探测与特征描述的背景下，高对比度成像必不可少，我们展示了经过完全优化的二维光瞳切趾，除了孔径本身的形状外，对光瞳平面切趾没有特定的几何约束。展示了圆形和分段孔径的掩模，有无中心遮挡和遮光条。我们现在可以针对任何孔径形状优化切趾器，还给出了 Subaru 望远镜、宇宙学与天体物理学空间红外望远镜（SPICA）以及詹姆斯·韦布空间望远镜（JWST）的最佳掩模示例。考虑了几个具有不同大小、位置、形状和对比度的高对比度区域。值得注意的是，这些优化产生的所有掩模往往都具有二元透射轮廓。
