... Image formation is typically described as a linear process. ... where, for 2-dimensional systems, the object coordinates are and the image coordinates are . Such a general description of a linear system is termed shift-variant, because the shape of , the impulse response (or point spread function, PSF), might change as the object position, , is shifted. ... Hence, the exit pupil geometry changes with field position, so the system response changes with field position (i.e., is shift-variant). ...
