Introduction To Fourier Optics Third Edition Problem Solutions |work|

Problems in this section introduce the coherent transfer function (CTF) and the optical transfer function (OTF). A notorious problem: “Compute the OTF for a system with a rectangular aperture and defocus. Plot the result as a function of spatial frequency.” The solution requires integration over overlapping pupil functions—a non-trivial geometric exercise.

: The impulse response of the system is given by the inverse Fourier transform of the coherent transfer function: Problems in this section introduce the coherent transfer

: Prove that the Fourier transform of a Gaussian function is a Gaussian function. more than any answer key

And that, more than any answer key, is the true solution. Problems in this section introduce the coherent transfer

Moving beyond the math to visualize how spatial frequencies represent physical objects.
