WebFeb 20, 2013 · In the commonly applied “knife edge method”, for example, an image over a straight edge is evaluated. But the latter determines the sharpness of an image and differs from the original meaning of lateral resolution. WebJan 10, 2009 · We revisited the well known Khosrofian and Garetz inversion algorithm [Appl. Opt.22, 3406-3410 (1983)] that was developed to analyze data obtained by the application of the traveling knife-edge technique. We have analyzed the approximated fitting function that was used for adjusting their experiment …
WebIntroduction With the growing role played by optical devices in measurement, communication, and photonics, there is a clear need for characterizing optical components. A basic and useful parameter, especially for imaging systems, is the Modulation Transfer Function, or MTF.
