WebFeb 17, 2016 · The Modulation Transfer Function (MTF) of an optical system if often determined with the use of a MTF chart ( image) or something similar. This chart has to be in focus in order for it to be used. But that made me wonder how these charts are used with telescopes (or microscopes). Since the image is only in focus with a telescope when the ... WebThe magnitude is known as the Modulation Transfer Function (MTF) and the phase portion is known as the Phase Transfer Function (PTF). In imaging systems, the phase component is typically not captured by the sensor. Thus, the important measure with respect to imaging systems is the MTF. ...
