Fourier optics is a branch of optics that uses the Fourier transform to analyze and understand the behavior of light waves. The field of Fourier optics has been extensively developed over the years, and one of the most influential books on the subject is "Introduction to Fourier Optics" by Joseph W. Goodman. In this blog post, we will provide an overview of the book and its solutions, as well as discuss the key concepts and takeaways from the work.
