Intended for engineers and scientists who need to make hardware, software, or procedural modifications, this book explains the design and instrumentation of Michelson-interferometer-based Fourier transform spectrometers. The author defines the signal-to-noise ratio and the principles of interferometer operation, then describes the FT spectrometer's motion components, analog-to-digital conversion process, detection system, and optical components.
