Moving beyond the math to visualize how spatial frequencies represent physical objects.
: This chapter is rich with practical applications. Problem 4-4 offers a "particularly simple and satisfying proof," often related to a key theorem in diffraction theory, like the convolution theorem. Problem 4-11 asks students to derive a fundamental property of diffraction gratings, while Problem 4-12 introduces a simple yet powerful method for calculating a grating's diffraction efficiency. Problem 4-18 is an excellent exercise for understanding the fascinating phenomenon of self-imaging (the Talbot effect).
