WebApr 1, 1993 · The spatial resolution (CTF and MTF) is measured as a function of spatial frequency and the standard deviation of the corresponding Gaussian PSF is derived. 1. Introduction The most important physical properties of such glasses are reported in ref. [5]. 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…
