  Borrowing methods and formulas from Prof. Goodman's classic Introduction to
Fourier Optics textbook [1], I have developed a software package [2] that has
been used in both industrial research and classroom teaching [3]. This paper
briefly describes a few optical system simulations that have been used over the
past 30 years to convey the power and the beauty of Fourier Optics to our
students at the University of Arizona's College of Optical Sciences.
