累积重建器（CuRe）是一种针对Shack-Hartmann波前传感器测量的光前直接重建器。本文将该算法应用于实际的望远镜几何，并讨论了从修正的Hudgin几何到Fried几何的过渡。在讨论了噪声的传播之后，我们分析了算法的复杂性。数值测试结果表明，该算法速度快、精度高，可用于超大望远镜自适应光学系统。
The Cumulative Reconstructor (CuRe) is a new direct reconstructor for an optical wavefront from Shack-Hartmann wavefront sensor measurements. In this paper, the algorithm is adapted to realistic telescope geometries and the transition from modified Hudgin to Fried geometry is discussed. After a discussion of the noise propagation, we analyze the complexity of the algorithm. Our numerical tests confirm that the algorithm is very fast and accurate and can therefore be used for adaptive optics systems of Extremely Large Telescopes.
