A novel method of reconstructing wavefront aberrations by use of Zernike polynomials for radial shearing interferometers is discussed. This method uses matrix formalism to calculate the Zernike coefficients of a wavefront under test and shows the validity of reconstructing an arbitrary wavefront aberration from an interferogram taken by a radial shearing interferometer. We also propose a new interferometer setup to determine the shape and the direction (concave or convex) of wavefront aberration in a single measurement.
讨论了一种利用泽尼克多项式重建径向剪切干涉仪波前像差的新方法。该方法使用矩阵形式来计算被测波前的泽尼克系数，并证明了从径向剪切干涉仪拍摄的干涉图重建任意波前像差的有效性。我们还提出了一种新的干涉仪设置，以便在单次测量中确定波前像差的形状和方向（凹或凸）。
