The measuring system was composed of a lens array and a detector. The wavefront detection of a large aperture laser beam could be realized by controlling the distance between the lenses and the size of the lens. The influence of different duty cycle factors on the accuracy of the wavefront reconstruction under the same arrangement and different arrangement conditions was simulated and analyzed. The simulation results showed that when the sub-lenses of the system were not in close contact, the reconstruction accuracy of the duty factor of 0.8 was close to that of the case of the duty factor of 1. Within a certain detection range, the hexagonal arrangement of 19 lenses and the arrangement of 8 \u00d7 8 lens arrays had a high wavefront restoration accuracy; both were lower than 0.10 \u03bb. The system proposed in this paper was suitable for measuring a large aperture laser beam, providing a new idea for measuring and analyzing the quality of large aperture laser beams. It also has an important significance for improving the measurement accuracy of the beam quality.<\/jats:p>","DOI":"10.3390\/s23020623","type":"journal-article","created":{"date-parts":[[2023,1,5]],"date-time":"2023-01-05T05:29:48Z","timestamp":1672896588000},"page":"623","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Simulation Analysis of a Wavefront Reconstruction of a Large Aperture Laser Beam"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9071-5816","authenticated-orcid":false,"given":"Gangyu","family":"Wang","sequence":"first","affiliation":[{"name":"Key Laboratory of Atmospheric Optics, Anhui Institute of Optics and Fine Mechanics, Hefei Institutes of Physical Science, Chinese Academy of Sciences, Hefei 230031, China"},{"name":"Science Island Branch of Graduate School, University of Science and Technology of China, Hefei 230026, China"},{"name":"Advanced Laser Technology Laboratory of Anhui Province, Hefei 230037, China"}]},{"given":"Zaihong","family":"Hou","sequence":"additional","affiliation":[{"name":"Key Laboratory of Atmospheric Optics, Anhui Institute of Optics and Fine Mechanics, Hefei Institutes of Physical Science, Chinese Academy of Sciences, Hefei 230031, China"},{"name":"Advanced Laser Technology Laboratory of Anhui Province, Hefei 230037, China"}]},{"given":"Laian","family":"Qin","sequence":"additional","affiliation":[{"name":"Key Laboratory of Atmospheric Optics, Anhui Institute of Optics and Fine Mechanics, Hefei Institutes of Physical Science, Chinese Academy of Sciences, Hefei 230031, China"},{"name":"Advanced Laser Technology Laboratory of Anhui Province, Hefei 230037, China"}]},{"given":"Xu","family":"Jing","sequence":"additional","affiliation":[{"name":"Key Laboratory of Atmospheric Optics, Anhui Institute of Optics and Fine Mechanics, Hefei Institutes of Physical Science, Chinese Academy of Sciences, Hefei 230031, China"},{"name":"Advanced Laser Technology Laboratory of Anhui Province, Hefei 230037, China"}]},{"given":"Yi","family":"Wu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Atmospheric Optics, Anhui Institute of Optics and Fine Mechanics, Hefei Institutes of Physical Science, Chinese Academy of Sciences, Hefei 230031, China"},{"name":"Advanced Laser Technology Laboratory of Anhui Province, Hefei 230037, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"645","DOI":"10.5768\/JAO202041.0409001","article-title":"Study on parameters measurement technology of high energy and high power laser","volume":"41","author":"Li","year":"2020","journal-title":"J.
