| 摘 要： | 提出了一种适用于哈特曼-夏克波前传感器的环形子孔径拼接检测技术的拼接复原算法.该算法通过建立各个环形子孔径内有效的哈特曼-夏克斜率数据和全孔径波前相位的关系,避免了环形子孔径区域的波前复原过程,从而有效地解决了环形子孔径区域的哈特曼-夏克波前传感器有效采样率低的问题.算法对斜率测量噪声较不敏感,具有较好的抗噪声干扰的能...

| Abstract: | A new algorithm is proposed for annular subaperture stitching technology based on Hartmann-Shack wavefront sensor.The algorithm can reconstruct the whole-aperture wavefront without reconstructing annular subaperture wavefront.The algorithm is feasible for the limited Hartmann sampling frequency in annular subaperture.By evaluating the sensitivity of the algorithm to the measurement noise of wavefront gradient data,the algorithm is not sensitive to the measurement noise of the wavefront gradient.The algorith... |
