Abstract

Atmospheric turbulence causes refractive index fluctuations, and atmospheric molecules absorb and scatter light wave energy, causing the power density of the laser to reach the target to decrease, restricting the application performance of advanced optoelectronic systems. Precision optoelectronic equipment has problems such as long development cycles and difficulty in quality control. Digital twins have low cost to establish digital models, can be quickly iterated, and have great potential in system analysis and diagnosis. According to the laser atmospheric transmission physical model and performance evaluation requirements, the laser transmission model is constructed and integrated in the digital space, and the C++ language, Qt (Q Toolkit) platform and multi-threaded parallel processing technology is used to develop and test the software system. Provides practical software tools for laser transmission performance evaluation and system parameter optimization design. With the help of the software system, the functional relationship of the refractive index structure constant, wind speed, absorption coefficient and extinction coefficient profile with height changes as well as the energy intensity distribution of the target surface spot can be calculated and visualized.
