In the process of installation and debugging of the plenoptic sensor, due to the existence of uncertain factors, assembly errors exist among the components, which adversely affect the distortion wavefront detection of the plenoptic sensor. In this paper, a numerical simulation model of the plenoptic sensor is established, the Zernike polynomial method is used to simulate the distorted wavefront of different turbulence intensities, and the phase reconstruction error RMS of the plenoptic sensor is used as an evaluation index to simulate and analyze the assembly errors that may occur during installation and commissioning. Through simulation research, it is found that the assembly error of the plenoptic sensor in the installation and debugging process will reduce the wavefront detection accuracy of the plenoptic sensor, and the degree of influence of the assembly error on the wavefront detection accuracy has a certain relationship with the turbulence intensity. The influence law of assembly errors with different turbulence intensities, different error types and different error ranges on the wavefront detection of the plenoptic sensor is summarized, which has guiding significance for the installation and debugging of the plenoptic sensor and the analysis of the wavefront detection error.
