    摘要
  • 摘要: 狭缝式调制传递函数测试系统可以测试光纤倒像器的调制传递函数，但由于测试过程中较多的人工参与，使得调制传递函数测试结果的重复性较差。针对影响光纤倒像器调制传递函数测试重复性的数据采样、积分时间以及人眼疲劳特性进行了分析，给出了针对数据采样和积分时间的解决方法，针对人眼疲劳特性提出了基于人眼时间递增因子的加权修正方法。对6块光纤倒像器的调制传递函数进行了三批次测试，并对测试结果进行了直接校正和加权修正的比较，结果表明：加权修正较好地解决了测试重复性问题，被测6块光纤倒像器加权修正后的调制传递函数最大重复性偏差不超过7%。
    Abstract: As an optical component for transferring image, fiber-optic image inverter has been extensively used in low-light-level image intensifier. The modulation transfer function (MTF) test system, on which slit is used, can be used to test the fiber-optic inverter-s MTF. But there is too much artificial participation during MTF testing, and the repeatability of inverter-s MTF is generally bad. Data sampling, integrating time and eyestrain which affected the repeatability of inverters MTF were respectively analyzed, the solution related to data sampling and integrating time was given, and the weighted correction method for eyestrain was presented. According to the six fiber-optic inverter-s MTF testing results and the comparison between direct correction and weighted correction of them, it is shown that the weighted correction solves the repeatability of inverter-s MTF well, and the maximum deviation for repeatability is less than 7%.
