| 摘 要： | 调制传递函数(Modulation Transfer Function,MTF)是评价成像系统成像质量的重要指标。介绍了用MTF评价光电摄像系统成像质量的方法。采用电荷耦合器件(Charge Coupled Device,CCD)自扫描接收通过MSFC_IV中焦和短焦平行光管后的被测试样的星点图样,经数据采集、转换及处理,定量地给出了被测试样的MTF值。结果表明,该方法能够快速、准确地定量评价光电摄像系统的成像质量。

| Abstract: | The modulation transfer function(MTF) is a means of characterizing the image quality of the optical system.The method of measuring the photoelectric camera system is recommended with MTF.A simple and quick method for measuring MTF was presented.Star image tested by MSFC-IV middle and short-focus collimator,and sample was sampled by Charge Coupled Device-CCD automatically. The measurement method is easier and simpler,and provides a fast and precise MTF measurement for the photoelectric camera system. |
