This paper describes a novel method used to evaluate heliostat misalignment and its experimental verification. This method provides a different way of visualizing beam centroid pointing errors by generating the complete deviation curve for each axis. This, for example, would be useful for verifying a heliostat’s correct alignment by using a measurement performed out of the receiver target, using these traces to calculate its reflection’s expected location, given a known misalignment. This measurement could be performed during operation simply by including a reflective element in the heliostat and two detector arrays on the tower’s surface. This model has been tested for various types of misalignments of a heliostat at different hours, dates, and heliostat locations. The simulation results have been validated by using an experimental setup at a scale of 1:100. info:eu-repo/grantAgreement/ES/DGA/T20-17R info:eu-repo/grantAgreement/ES/MINECO/RTC-2016-5226-3 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.669 2019 OPTICS 19 / 97 = 0.196 2019 Q1 T1 1.533 2019 Atomic and Molecular Physics, and Optics 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Preciado, J.
