This book presents the fundamentals of spectral imaging and discusses the technical challenges in new and emerging applications including hardware and software implementations. Different innovative solutions for applications are discussed such as nanophotonics including plasmonic photonic bandgap and nanowire based structures in developing compact, high performance multispectral imagers. Image processing, analyzing, and interpretation of spectral data are discussed. Various applications of spectral imaging including food quality testing, dermatology, point-of-care diagnosis are presented.
