摘要
本文介绍了一种新型消色差相移器（APS），适用于零偏干涉测量和日冕仪，基于一对交叉分束立方体，非常适合装备未来用于搜寻位于宜居带的系外行星的星载仪器。我们展示了该 APS 的基本原理，并讨论了其在零偏日冕仪望远镜或稀疏孔径干涉仪（无论是 Fizeau 型还是 Michelson 型）中的可能实现方式。文中还提供了关于透射图样的预期性能以及初步的公差分析。结果表明，该装置成本低廉、结构紧凑，且具有合理的制造公差和成本。

备注
This paper has been withdrawn by the authors due to wrong phase-shifts of the beams transmitted by the semi-reflective cubes. It follows that an achromatic and non polarized null is only achievable with two of the four considered telescopes. A revised paper will be issued soon
