全光波前传感器将瞳面和像面的测量结合起来，同时从不同角度获取波前信息，能够对望远镜上方的体积进行采样，提取大气湍流的层析信息。在描述了工作原理后，利用实验室装置验证了测量瞳孔平面波前的能力。本文还对其他波前传感器进行了比较讨论。
The plenoptic wavefront sensor combines measurements at pupil and image planes in order to obtain wavefront information from different points of view simultaneously, being capable to sample the volume above the telescope to extract the tomographic information of the atmospheric turbulence. After describing the working principle, a laboratory setup has been used for the verification of the capability of measuring the pupil plane wavefront. A comparative discussion with respect to other wavefront sensors is also included.
