Cemented-prism static Fourier spectrometers

摘要

In the 1980s, research expanded beyond the traditional path-difference scanning Fourier spectrometer, both in Russia and abroad, with the primary result being development of static Fourier spectrometers. These instruments enable the spectrum of a source to be obtained by recording and processing a spatially localized interferogram. A single optical module using cemented prisms provides better rigidity and tuning stability than the mirrors, beamsplitters, and dihedral prisms used in path-difference interferometers. Experience in the design and operation of cemented-prism static Fourier spectrometers has led to an interest in exploring the range of existing spectrometers and conducting a comparative analysis.
