A modulation transfer function (MTF) measuring technique is described that employs the optical matched filter (OMF). It is shown that this technique is mathematically equivalent to the multiple-sine-slit microdensitometer (MSSM) MTF measurement approach. Similarities and differences in the implementation of the two methods are discussed. Both theoretical and experimental matched filter results are investigated. A method for extending the OMF to high spatial frequencies is discussed.
本文描述了一种采用光学匹配滤波器（OMF）的调制传递函数（MTF）测量技术。结果表明，该技术在数学上等同于多正弦狭缝显微密度计（MSSM）的MTF测量方法。讨论了两种方法在实现过程中的异同。对理论和实验匹配滤波器结果均进行了研究。还讨论了将OMF扩展到高空间频率的方法。
