Ct transfer function
WebThe modulation transfer function, or MTF, is a parameter used to evaluate the performance of a lens. MTF provides a quantitative and standardized way to characterize optical systems, so the metric is used by optical designers and microscopists alike to compare lenses and determine the ideal one for an imaging system. http://ws.binghamton.edu/fowler/fowler%20personal%20page/EE301_files/EECE%20301%20Note%20Set%2029%20CT%20Transfer%20Function.pdf
