A Zernike-polynomials-based wavefront reconstruction method for lateral shearing interferometry is proposed. Shear matrices are calculated using matrix transformation instead of mathematical derivation. Simulation results show that the shear matrices calculated using the proposed method are the same as those obtained from mathematical derivation. The advantage of the proposed method is that high order shear matrices can be obtained easily; thus, wavefront reconstruction can be extended to higher order Zernike terms, and reconstruction accuracy can be improved.
提出了一种基于泽尼克多项式的横向剪切干涉术波前重建方法。利用矩阵变换而非数学推导来计算剪切矩阵。仿真结果表明，用该方法计算得到的剪切矩阵与通过数学推导得到的矩阵相同。该方法的优点是能够轻松获得高阶剪切矩阵；因此，波前重建可扩展到更高阶的泽尼克项，进而提高重建精度。
