Enhanced On-Site Characterization of Heliostat Surface via Direct Calculation of Reflected Beam’s Normal Vectors

In this study, the results obtained through the algorithm presented for calculating the surface error will be analyzed. This aims to achieve a more precise characterization of the heliostat surface, independent of external conditions such as environment or solar field configuration. This can be accomplished by acquiring data obtained through HelioscharPlus characterization system, which has been presented in previous works and is distinguished by being based on data measured in real conditions, providing insights into the actual operation of the heliostat. This measurement mode offers the possibility to apply refinement process to the results, crucial for enhancing the accuracy of the characterization and aligning it more closely with real-world conditions.
