A scintillation resistant sensor that allows retrieval of an input optical wave phase using a multi-aperture phase reconstruction (MAPR) technique is introduced and analyzed. The MAPR sensor is based on a low-resolution lenslet array in the classical Shack-Hartmann arrangement and two high-resolution photo-arrays for simultaneous measurements of pupil- and focal-plane intensity distributions, which are used for retrieval of the wavefront phase in a two stage process: (a) phase reconstruction inside the sensor pupil subregions corresponding to lenslet subapertures and (b) recovery of subaperture averaged phase components (piston phases). Numerical simulations demonstrate the efficiency of the MAPR technique in conditions of strong intensity scintillations and the presence of wavefront branch points.
介绍并分析了一种抗闪烁传感器，该传感器可使用多孔径相位重建（MAPR）技术来恢复输入光波相位。MAPR传感器基于经典夏克-哈特曼配置中的低分辨率微透镜阵列以及两个高分辨率光阵列，用于同时测量光瞳和焦平面强度分布，这两个光阵列在两个阶段的过程中用于恢复波前相位：（a）在与微透镜子孔径相对应的传感器光瞳子区域内进行相位重建，以及（b）恢复子孔径平均相位分量（活塞相位）。数值模拟证明了MAPR技术在强强度闪烁和存在波前分支点的条件下的有效性。
