Mastering the Fresnel and Fraunhofer approximations. The CTF, $H(f_x, f_y)$, is equal to the

The CTF, $H(f_x, f_y)$, is equal to the pupil function mapped into frequency coordinates. $$ H(f_x, f_y) = P(\lambda d_i f_x, \lambda d_i f_y) $$ Where $d_i$ is the image distance. The cutoff frequency occurs when the argument is $\pm w/2$. $$ \lambda d_i f_cutoff = \fracw2 \implies f_cutoff = \fracw2 \lambda d_i $$ $$ \lambda d_i f_cutoff = \fracw2 \implies f_cutoff

: The Fourier transform of a Gaussian function is given by:

A transparency with amplitude transmittance $t_1(x, y)$ is placed immediately in front of a positive lens of focal length $f$. The lens is illuminated by a normally incident plane wave of wavelength $\lambda$. Find the field distribution at the back focal plane.
