Modal analysis can be carried out by implementing a computer-generated hologram acting as a match filter in a spatial light modulator. In this work, a series of aspects to be taken into account in order to get the most out of this method are presented, aiming to provide useful operational procedures. First of all, a method for filter size adjustment based on the standard fiber LP-mode symmetry is presented. The influence of the mode normalization in the complex amplitude encoding-inherent noise is then investigated. Finally, a robust method to measure the phase difference between modes is proposed. These procedures are tested by wavefront reconstruction in a conventional few-mode fiber. info:eu-repo/grantAgreement/ES/DGA-FEDER/Construyendo Europa desde Aragón info:eu-repo/grantAgreement/ES/DGA-FEDER/E44-20R info:eu-repo/grantAgreement/ES/MICINN-AEI/PID2019-108598GB-I00/AEI/10.13039/501100011033 info:eu-repo/grantAgreement/ES/MICINN-AEI/PID2019-110927RB-I00/AEI/10.13039/501100011033 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.4 2022 CHEMISTRY, ANALYTICAL 29 / 86 = 0.337 2022 Q2 T2 INSTRUMENTS & INSTRUMENTATION 25 / 63 = 0.397 2022 Q2 T2 PHYSICS, APPLIED 57 / 160 = 0.356 2022 Q2 T2 NANOSCIENCE & NANOTECHNOLOGY 68 / 107 = 0.636 2022 Q3 T2 0.546 2022 Control and Systems Engineering 2022 Q2 Mechanical Engineering 2022 Q2 Electrical and Electronic Engineering 2022 Q2 4.7 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Collados, María Victoria Universidad de Zaragoza (orcid)0000-0002-3299-253X Martín, Juan C.
