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.
