Fourier Transform Infrared

This study describes the technique of Fourier transform infrared technology. The underlying theory is described in tandem with discussion of the instrumentation and its development to the present time. The fundamental advantages of the FT approach are described, and the physical principles are explained without recourse to rigorous mathematics. The various types of construction of the range of current commercial instruments are examined, and their advantages and disadvantages noted. In addition, there are descriptions of spectrometers built for special applications, such as space flight.
