Abstract
In this paper we propose a modification to the ordinary moving-optical–wedge interferometer used for Fourier transform spectrometry. The ordinary wedge interferometer suffers from asymmetry in the visibility pattern, asymmetry in the interferogram, large volume, large weight, and greater motion of the wedge. Our proposed interferometer is based on using two pair of wedges. This results in symmetry in visibility pattern, symmetry in interferogram, halved size, halved motion, and more throughput.
