摘　　要：目的为建立国防光学计量最高标准，研制光学传递函数（ＯＴＦ）标准望远镜．方法采用放宽制造公差、合理确定波像差水平的设计原则和方法，解决高精度检测光学结构参数，准确计算和测量ＭＴＦ及其不确定度评定等关键技术．结果６具两种工作视度的标准望远镜的计量性能均达要求，其ＭＴＦ扩展不确定度达到轴上０．０３，轴外０．０６．结论研制的ＯＴＦ标准望远镜的性能是迄今国际报道中最好的．Aim To develop OTF standard telescopes for the need of setting the optical measurement standard Methods The design principles and methods with the relaxed requirement of manufacturing tolerances and the appropriate level of wave aberrations were adopted The measurement of optical structure parameters, the calculations and measurements of MTF and the uncertainty evaluation of MTF were achieved Results Its MTF expanded uncertainties reached 003 on axis, 006 off axis Conclusion This result is the best in the world up to now
