Modulation Transfer Function (MTF) has been associated with measurement of performance of optical systems from the initial introduction of linear system analysis to this field. As the demand for higher quality, higher resolution optical systems has become prevalent, both designers and metrology scientists have begun investigating MTF as a mutual mode of quantifying the performance of optical systems. This article identifies the reasons for specification and measurement of MTF as a system characterization tool.
