热光模拟是对经典光线追迹法的一种改进，因为光学和激光技术的许多分支都必须处理热梯度。本文讨论了一种耦合有限元和射线追踪模拟工具的方法，通过处理有限元数据，使用分散的数据近似技术。通过将近似数据与高达1.75 kW的CO2激光器应用的测量值进行比较，验证了两个空间维度的实现接口。最后，讨论了在光学模拟中分析热梯度的好处和进一步的发展。
Thermo-optical simulation is a compulsory improvement of classical ray tracing, since many branches of optical and laser technology have to deal with thermal gradients. This paper discusses an approach for coupling FEM and ray tracing simulation tools by processing FE data using scattered data approximation techniques. The implemented interface for two space dimensions is being validated by comparing approximated data to measured values from a CO2 laser application of up to 1.75 kW. Finally, the benefits and further developments of analyzing thermal gradients in optical simulation are being discussed.
