对军用车辆瞄准具的MTF(调制传递函数)测试参数进行了研究,并且发展了用Sira Beck“Eros”装置进行测量的适当程序。运用对所有方位在单一空间频率下简化的MTF测试规范,减少了测试数据,从而为以后的评价工作提供了方便。进行此项测试的装置,可测量固定焦点目镜的视度装定情况、场曲和像散。我们还对关于建立综合性设计指标,减少控制质量的技术条件等问题进行了讨论。
MTF (Modulation Transfer Function) test parameters for military vehicle sights have been studied and appropriate procedures have been developed for measurements with Sira Beck “Eros” devices. By using simplified MTF test specifications for all azimuths at a single spatial frequency, the test data is reduced, thus facilitating future evaluations. The device for this test measures the visual fixation of fixed-focus eyepieces, field curvature and astigmatism. We also discussed the issues of establishing comprehensive design specifications and reducing the technical conditions for control quality.
