Using the four-dimensional simulation program of laser atmospheric transmission, the influence of the measurement range and accuracy of atmospheric parameters on the transmission effect of the whole layer in the process of laser atmospheric transmission was numerically analyzed. In the simulation process, by comparing the results of different measurement heights and the whole layer measurement, the parameter accuracy of the atmospheric parameters and the influence of the initial altitude on the transmission effect parameters are analyzed. It is concluded that after the measurement height is 4 km, the error between the measurement height and the whole layer gradually tends to be flat and the error is less than a certain range, and it is obtained that the variation trend of the error under different zenith angles is the same, which provides a basis for the measurement requirements and evaluation of atmospheric parameters.
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.
