Description:

The increased interest in imaging spectroscopy has arisen largely for technical reasons. This Tutorial Text first reviews the required background in optics, radiometry, imaging, spectral sensing and focal plane arrays. Then the principles of these subjects are applied to several specific problems to illustrate the way in which such instruments can be designed.

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.
