<title>Fourier spectrometers: design and technology problems</title>

Abstract

The principle of Fourier spectroscopy is shortly remembered. The advantages of Fourier spectroscopy with comparison to other spectroscopic techniques are presented. The design and construction of Fourier spectrometer. especially with high resolving power, require to overcome many mechanic, electronic and optic technological difficulties. The requirements related to some of them are extremely high. Some engineering problems. such as mirror motion irregularities during interferogram scanning, sampling density, influence of temperature instability, beam splitter construction and influence of water vapour are discussed and some ways to solve the problems are proposed.
