These notes arose from an interest in improving the quality and performance of multispectral imaging devices. I have also long been interested in instrumental spectroscopy, perhaps a subliminal Michigan influence. My masters' problem was done with an ancient Perkin Elmer spectrometer, Model 12, I think. It used a salt (NaCI) prism that was at risk in the humidity of Ann Arbor, and its slit had to be programmed for equal energy by the proper positioning of a string on a drum. Proper was found by trial and error.
My exposure to the design of an imaging spectrometer occurred at Ball Aerospace Systems while I was there on sabbatical. I thank them for their hospitality. I thank The University of Arizona for supporting me during this time.
I am indebted to the three critical readers of the manuscript: Don O'Shea, George Zissis, and Jack Cederquist. They did much to improve the final version. I also greatly appreciate the editorial and production efforts of Mary Kalbach Barnard. The good stuff is theirs; the misteaks are mine.
I dedicate this book, because once was not enough, to my patient and loving wife of more than forty years, who still wonders what I am doing in front of the computer and why I am using her phone.
