Introduction To Fourier Optics Third Edition Problem Solutions -

This chapter introduces the concepts of Coherent Transfer Functions (CTF) and Optical Transfer Functions (OTF).

Fresnel diffraction requires numerical evaluation of Fresnel integrals unless the distance $z$ is very large (Fraunhofer regime) or very small (Rayleigh-Sommerfeld regime).

Ensure all Fourier transform pairs maintain dimensional consistency (e.g., if spatial coordinates are in millimeters, spatial frequencies must be in cycles per millimeter). Test if a shifted input results in an

$I(\theta) = \left| \int_0^a J_0(2\pi \rho \sin \theta) \rho d\rho \right|^2$

The incoherent cutoff frequency ($2f_cutoff$) is twice the coherent cutoff frequency, meaning incoherent imaging passes higher spatial frequencies, but with reduced contrast compared to the "all-or-nothing" pass of the coherent system.
