摘　　要：探讨了复合形优化方法在光谱仪光学系统设计中的可行性和应用方法.以反射式光栅光谱仪光学系统为例,建立了优化数学模型,以焦平面像差极大值为目标函数,光学器件的参数、物理尺寸和相对几何位置等为约束条件,编写了优化程序,得出了最大像差为0.043 mm的一组最优化方案.与专业设计软件作了对比,在某些光学设计应用方面,复合形法的优化效果具有较高的实用性和优化效率.The feasibility and application method of the constrained complex method in designing spectrometers optical system is discussed.Take a reflective grating spectrometer as an example,a mathematical model for optimization was established and an optimizing program was given,where the maximum aberration value was considered as the target function,while the parameters,dimensions and geometrical position of the optical parts were regarded as constrained condition.The optimized result features a maximum aberration...
