人们意识到，在未来十年左右的时间里，太阳系外行星的直接成像可能在技术上是可行的，这激发了最近对高对比度成像的大量研究。我们贡献了几个设计想法，所有这些都可以被描述为成形的瞳孔日冕图。我们提供了一个完整的和统一的一维形状的瞳孔设计的调查，其中一些已经发表在我们以前的论文中。我们还介绍了一种很有前途的新设计，我们称之为条形码面具。有了这些掩膜，我们可以在相当大的发现区域和吞吐量下实现所需的对比，但最重要的是，它们可能是最容易制造的，因此可能最经得起精细的分析。
The realization that direct imaging of extrasolar planets could be technologically feasible within the next decade or so has inspired a great deal of recent research into high-contrast imaging. We have contributed several design ideas, all of which can be described as shaped pupil coronagraphs. We offer a complete and unified survey of one-dimensional shaped pupil designs, some of which have been published in our previous papers. We also introduce a promising new design, which we call bar-code masks. With these masks we can achieve the required contrast with a fairly large discovery zone and throughput, but most importantly they are perhaps the easiest to manufacture and might therefore stand up best to refined analyses.
