摘　　要：讨论了样条函数在光学器件设计和优化过程中的建模方法与应用。提出了用样条函数进行太阳能会聚器的优化设计。根据太阳能会聚器曲面的设计要求,首先讨论了抛物面与高次非球曲面的光学性能,然后给出了样条函数的数学模型和优化设计过程。基于光学设计软件CODE V的计算机仿真结果表明,它与通常的抛物面会聚器相比,样条函数方法具有太阳能转换效率高、系统可实现间断跟踪太阳和成本低等优点。Modeling method and application of a spline function in design and optimization of a optical device are discussed. According to design of concentrator, first parabolic mirror and aspheric are discussed, then a mathematical model and optimization are described using a spline function. Some results are obtained by using optical design of software CODE V. They show that the device with spline function has high efficiency , discontinuous tracking system and less expensive cost to compare with parabolic concentrator. 
