Since the optical transfer function (OTF) is defined as the Fourier transform of the point-spread function (PSF), it is generally speaking a complex-valued function of spatial frequency. The projection of a specific periodic pattern is represented by a complex number with absolute value and complex argument proportional to the relative contrast and translation of the projected projection… WebTemplate with dotted lines with descend- ing width is used to retrieve Contrast Transfer Function (CTF) and is mathematical- ly translates into a sinusoidal response (MTF) using serial...
