Development and validation of the meteorological optical range definition reproduction method using array optical components
In this study, we proposed a method for reproducing the meteorological optical range (MOR) definition using array optical components and constructed a system architecture. Thirty light-emitting diodes were selected via a dual evaluation system for spectral homogeneity and purity. Combined with an optimized optical architecture-including dual free-form lenses and a microlens array-and a long short-term memory-non-dominated sorting genetic algorithm II-the system achieved 96% irradiance uniformity over the 65 × 65-mm range, < 3.6° beam divergence, and a spectral matching error of -4.24%. This approach enables accurate MOR definition reproduction, enhancing traceability and supporting the calibration of visibility measurements.
