本文详细分析了零位光栅设计要求,各参数之间的关系,在此基础上得出了零位光栅设计准则及优化设计的数学模型。並指出其设计问题属大范围的、离散的0—1规划问题,可以用非常规方法解决。文中叙述了运用动态规划思想的动态设计方法。介绍了计算原理、计算过程及程序设计思想。动态设计方法既减少了设计计算时间,又能得出满意的计算结果,所以它是行之有效的设计方法。
In this paper, the design requirements of zero grating and the relationship between the parameters are analyzed in detail. Based on this, the design rules of zero grating and the mathematical model of optimal design are obtained. And pointed out that the design problem is a wide range of discrete 0-1 planning problems, can be used unconventional methods to solve. The article describes the dynamic design method using dynamic programming ideas. Introduced the calculation principle, the calculation process and the programming idea. The dynamic design method not only reduces the design calculation time, but also obtains the satisfactory calculation result, so it is an effective design method.
