Concisely summarizing imaging spectrometer instrumentation, this book divides current imaging spectrometer modalities into two tiers. The first tier describes how any given spectrometer acquires spectral data, specifically, using frequency or time domain techniques. The second tier explains how the spectrometer divides the light after entering the system. Each instrument s introduction includes a system schematic as well as a discussion of theoretical foundations, calibration issues, and design considerations. The book also explores common spectral processing algorithms and provides a comparison between the different forms of instrumentation."
