1. Detector resolution: MTF (modulation transfer function)
1.1 Fourier transform and spatial frequency
Reading this article will be facilitated by a reminder of some basic Fourier analysis concepts. Any signal (an image) at the input or output of a detector, defined by a function E (x, y) [signal intensity at point x = (x, y)], can be written as :
( 1 )...
