Abstract

There have been made some attempts to transfer the advantages of FT-IR to industrial use. Commercially available research grade instruments have traditionally been large and rather expensive. However, in many potential applications only medium resolution is required, especially when measuring liquid or solid samples. This means that the mirror displacement in a Michelson interferometer remains short and computation of the Fourier transform can be executed by a small computer. Medium resolution gives also other advantages in designing a spectrometer; simple source and detector optics, less severe requirements for mirror transport, and a small size.
