Abstract
The development of a static Fourier-transform spectrometer based on a single Wollaston prism, two polarizers and a compact 2D detector array is discussed. The Wollaston prism is of a modified configuration so t hat for an extended light source the interferogram fringes are localis ed just behind the exit face of the prism. This leads to an ultra-comp act design for a Fourier-transform spectrometer (mounted within a 40 m m cube) that has a resolution of approximately 230 cm(-1) and an angul ar acceptance of +/-5 degrees.
