Shack-Hartmann波前传感器(SHWS)是自适应光学显微镜中用于波前传感的重要工具。然而,由复杂波前相位分布引起的畸变点阵限制了其探测性能。本文提出一种基于深度学习的波前探测方法,该方法结合了基于点扩散函数图像的泽尼克(Zernike)系数估计和波前相位分布拼接。该方法不仅仅使用每个子孔径的质心位移,而是通过子孔径的点扩散函数分布估计局部波前对应的Zernike系数,然后拼接局部波前进行重建。本文所提方法可实现高精度的复杂波前检测,获得的波前残差均方根误差值显著降低,在自适应光学显微中具有极大应用潜力。
The Shack-Hartmann wavefront sensor (SHWS) is an essential tool for wavefront sensing in adaptive optical microscopes. However
the distorted spots induced by the complex wavefront challenge its detection performance. Here
we propose a deep learning based wavefront detection method which combines point spread function image based Zernike coefficient estimation and wavefront stitching. Rather than using the centroid displacements of each micro-lens
this method first estimates the Zernike coefficients of local wavefront distribution over each micro-lens and then stitches the local wavefronts for reconstruction. The proposed method can offer low root mean square wavefront errors and high accuracy for complex wavefront detection
and has potential to be applied in adaptive optical microscopes.
