Before diving into the calculus, sketch the expected intensity pattern. If the aperture is a square, expect a 2D sinc function; if it's a circle, expect an Airy disk.
(Lenses as phase transformers and Fourier transform operators).

Setting up the Fresnel or Fraunhofer diffraction integrals correctly based on the aperture shape and distance.
Whether you find a copy at your university library or discuss the steps on an online forum, engaging with these solutions—critically and ethically—transforms the study of Fourier optics from a memorization of transforms into a genuine intuition for how light travels, spreads, and images. When tackling problem solutions from the text, follow
You will encounter a recurring cast of functions across all problem sets. Ensure you know their exact definitions and transform pairs:
PSF(x) = |h(x)|^2 = |∫∞ -∞ P(u) exp(i2πux) du|^2 = |∫∞ -∞ circ(u) exp(i2πux) du|^2 = (2J1(2πx))/(2πx))^2 Ensure you know their exact definitions and transform
