This method takes a conical array composed of flexible fibers to sample and shrink the cross-section spot of the laser beam, facilitating low-distortion shooting with a charge-coupled diode (CCD) camera, and adopts homogenized processing and algorithm analysis to correct the spot. This method is experimentally proven to achieve high-accuracy measurements with a decimeter-level spot-receiving surface, millimeter-level resolution, and high tolerance in order to incite skew angle. Comparing the measured spot under normal incidence with the real one, the root mean square error (RMSE) of their power in the bucket (PIB) curves is less than 1%. When the incident angle change is between \u22128\u00b0 and 8\u00b0, the RMSE is less than 2% and the measurement error of total power is less than 5% based on the premise that the fiber\u2019s numerical aperture (NA) is 0.22. The possibility of further optimizing the measurement method by changing the fiber parameters and array design is also reported.<\/jats:p>","DOI":"10.3390\/s22207892","type":"journal-article","created":{"date-parts":[[2022,10,18]],"date-time":"2022-10-18T00:31:01Z","timestamp":1666053061000},"page":"7892","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Study on Laser Parameter Measurement System Based on Cone-Arranged Fibers and CCD Camera"],"prefix":"10.3390","volume":"22","author":[{"given":"Jie","family":"Luo","sequence":"first","affiliation":[{"name":"School of Environmental Science and Optoelectronic Technology, University of Science and Technology of China, Hefei 230026, China"},{"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":"State Key Laboratory of Pulsed Power Laser Technology, Hefei 230037, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"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":"State Key Laboratory of Pulsed Power Laser Technology, Hefei 230037, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"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":"State Key Laboratory of Pulsed Power Laser Technology, Hefei 230037, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Silong","family":"Zhang","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":"State Key Laboratory of Pulsed Power Laser Technology, Hefei 230037, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenyue","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Environmental Science and Optoelectronic Technology, University of Science and Technology of China, Hefei 230026, China"},{"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":"State Key Laboratory of Pulsed Power Laser Technology, Hefei 230037, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenlu","family":"Guan","sequence":"additional","affiliation":[{"name":"School of Environmental Science and Optoelectronic Technology, University of Science and Technology of China, Hefei 230026, China"},{"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":"State Key Laboratory of Pulsed Power Laser Technology, Hefei 230037, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"054201","DOI":"10.1117\/1.3580660","article-title":"Analysis and modeling of a high\u2212power Yb: Fiber laser beam profile","volume":"50","author":"Kaplan","year":"2011","journal-title":"Opt.
