Horizontal and angular mechanical\nerrors appear between the incident light and the dualwedge\ncentral optical axes. By building a mathematical\nmodel of an ideal dual-wedge scanning trajectory and a\ntrajectory affected by mechanical errors, this paper analyzes\nthe types and degree of influence on the scanning\nprocess, as well as the sensitivity of scanned images\nto different errors. Results show that the angular\nerror has the most significant influence on the scanning\nimage accuracy, in terms of trajectory shape and coverage.\nTo correct the angular error, the two degrees-offreedom(\nDOF) flexible fine-tuning mechanism is customized\nbased on the principle of the cantilever beam\ntype. After finite element analysis(FEA) and experimental\nvalidations, the fine-tuning mechanism can guarantee\nthat the angular error in the dual-wedge central optical\naxes will be lower than 0.05 degree, thus ensuring\nscanning trajectory accuracy.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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","url":"https://opticapublishing.figshare.com/collections/Effect_of_Mechanical_Error_on_Dual-Wedge_Laser_Scanning_System_and_Error_Correction/3963888/1","contentUrl":null,"metadataVersi
