Abstract

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.
