Abstract: The ability of plenoptic sensor to reconstruct wavefront phase was studied by means of software 
simulation, where FFT algorithm was used to simulate the wave propagation and diffraction effects, 
Zernike polynomial was used to simulate the aberration, and the wavefront phase was reconstructed 
according to the theory of plenoptic mapping and inverse plenoptic mapping. The wavefront phase 
reconstruction of the first 22 single-order aberrations was studied, and the reconstruction results 
of the primary aberration and the secondary aberration were compared and analyzed. In addition, 
multiple sets of simulation experiments were conducted for the wavefront reconstruction of the 
complex aberrations, and the reconstruction errors of the lower-order complex aberrations and 
higher-order complex aberrations are also compared. The results show that the plenoptic sensor 
can reconstruct the wavefront phase regardless of the single-order aberration or the complex 
aberrations, and the phase reconstruction effect for the lower-order aberration is better than 
that of the higher-order aberration.

Key words: plenoptic sensor, Zernike polynomial, aberration, phase reconstruction
