Advantages of Cube Corner Interferometers in High Resolution Fourier Transform Spectroscopy

Cube corner interferometers are now well accepted in practise in Fourier transform spectroscopy (FTS). However, there are quite many special qualities of cube corner interferometers which are completely different from conventional plane mirror interferometers. None of these characteristics are very well-known. In this paper we will introduce some which are very important in high resolution FTS. We will do this by introducing all high resolution cube corner interferometers constructed or under construction in Finland.
