I used this book side-by-side with Hecht for a course entitled "Fourier Theory in Optics". I found Steward to be much more clear and readable, though at times less mathematically rigorous than Hecht. For someone who wants to learn what Fourier Optics is, I highly recommend this book. Steward starts from the absolute basics of Physical Optics and builds up to relatively advanced applications of Fourier series and transforms as they relate to Optics.
One particular thing which I found he stresses more than Hecht is the relationship between the Fourier transform of the aperture function and the diffraction pattern. I found Hecht to be very unclear about this to the extent that you could read many pages of his description of Fourier series' and transforms and still have no idea what it has to do with Optics.
However, I must add that Hecht goes into more depth in subjects like the calculation of the MTF and convolution.
In short, this is the best book I am aware of for learning Fourier optics from scratch but as the name indicates it is an introduction, albeit a rather comprehensive one.
