Abstract

The development of a novel static Fourier-transform spectrometer based on two Wollaston prisms, two polarizers, and a compact two-dimensional detector array is described. The wavelength calibration is fixed by the geometry of the prisms and the detector array and is therefore inherently stable. The Wollaston prisms are fabricated from materials with opposite sign on birefringence which gives a significantly increased field of view compared with existing Wollaston prism based Fourier-transform spectrometers. The spectrometer operated in the visible region of the spectrum, has a resolution of 350 cm(-1), an aperture of 6 x 4.6 mm, and a field of view of +/- 10 degrees. The optical assembly is interfaced to a laptop computer resulting in a rugged portable instrument with no moving parts
