本文综述了光学仪器精度计算的传统方法及其存在问题,提出了用计算机进行精度计算的方法,给出了用直接优化法进行精度分配与构造参数计算的程序框图和五组技术水平相差很远的初始设计变量,以及经过运算后获得相同优化结果的实例.初步实践表明,精度计算优化方法,不仅可以摆脱多次调整反复试算的繁重劳动,而且可能找到满足一定约束条件下理论上可能获得的最优设计方案,这是传统的试算法无法实现的。
In this paper, the traditional method and its existing problems in the precision calculation of optical instruments are reviewed. The method to calculate the precision by computer is put forward. The block diagram of the precision distribution and the calculation of the structure parameters by using the direct optimization method is far from the technical level of the five groups. Of the initial design variables, as well as after the operation to obtain the same optimization results of the example.Preliminary practice shows that the precision calculation and optimization methods, not only can get rid of multiple heavy trial and error repeatedly laborious and may find some constraints may be theoretically possible to obtain The optimal design, which is the traditional trial method can not be achieved.
