Abstract
From the functional analysis of the field-widened Michelson interferometer developed by A. Girard in 1970, this paper investigates the design of a new generation of interferometer with two input and output channels, combining the advantages of a simplified optical design with highly compact geometry and enhanced system performance. The optical design is characterized as follows: direct location of the interferometer in the front-end optics' focal plane, location of the fringes outside the interferometer (thereby directly over the detector plane), and optimization capability with a relatively low aperture number. The system-level performance of an on-board imaging Fourier Transform Spectrometer (FTS) based on such an interferometer is discussed.
