Recently we have proposed an iterative algorithm for subaperture stitching interferometry. It was referred to as the subaperture stitching and localization (SASL) algorithm. The limitation of the algorithm is that three-dimensional Cartesian coordinates are required, whereas the standard spherical interferometer can read out only the phase differences on the pixels. On the basis of the SASL algorithm, we propose an iterative algorithm for a spherical subaperture stitching test. It deals with data directly from the spherical interferometer. Unknown radii of best-fit spheres for a null test of subapertures are included in the optimization variables. The developed algorithm inherits the advantages of the SASL algorithm.
最近，我们提出了一种用于子孔径拼接干涉测量的迭代算法。它被称为子孔径拼接与定位（SASL）算法。该算法的局限性在于需要三维笛卡尔坐标，而标准球面干涉仪只能读出像素上的相位差。基于SASL算法，我们提出了一种用于球面子孔径拼接测试的迭代算法。它直接处理来自球面干涉仪的数据。子孔径零测试的最佳拟合球面的未知半径包含在优化变量中。所开发的算法继承了SASL算法的优点。
