焦面哈特曼传感器(光场相机)具有同时测量距离信息和波前相位信息的优点,国内目前还没有相关研究.本文对焦面哈特曼传感器的点目标波前相位复原能力进行了研究.首先从结构上将焦面哈特曼传感器与其他常用的波前传感器作了简单的比较,然后对焦面哈特曼的成像原理进行了推导说明,最后采用 MATLAB 软件对焦面哈特曼传感器的远场光斑进行仿真,通过相应的斜率估计算法,进行波前复原.仿真结果表明,焦面哈特曼传感器能够实现波前复原,从而达到了仿真验证的目的.

Plenoptic camera could measure the distance and wavefront information simultaneously, but there aren’t any related researches in China. In this paper, we researched plenoptic camera’s wavefront phase recovery ability for a point source. Firstly, the structure between plenoptic camera and other common wavefront sensors was compared. Then, imaging principle of plenoptic camera was explained. Finally, farfield spot was simulated by using MATLAB, and wavefront phase was reconstructed with the relevant slope evaluated algorithm. The simulation results show that plenoptic camera has the ability of recovering wavefront phase.
