Abstract
Because of the development of detector arrays stationary interferometric spectrometers now have many applications in the visible and IR; however, these same array sizes make it impractical to design a single Fourier optics system with the necessary large field angles required for the terahertz region. By dividing the Fourier optics into independent components in each arm of an interferometer we show that the aberrations are dramatically reduced, while the same theoretical throughput as in the scanning Michelson interferometer is maintained.
