Paper Abstract
There are two different types of beam combination: Fizeau interferometer and Michelson interferometer.
Pupil plane beam combination is referred as Fizeau interferometer. On the other hand, image plane beam
combination is referred as Michelson interferometer. In general, working principles of Michelson
interferometers are based on double Fourier interferometry. It is possible to acquire two-dimensional
spatial and one-dimensional spectral information of the sky by applying a Fourier transform spectrometer
algorithm and the Van Cittert-Zernike theorem. This imaging scheme is referred to as the double Fourier
interferometry. On the other hand, it is so far thought to be difficult to perform the imaging with a Fizeau
interferometer, because Fizeau interferometers basically don't have a delay line that is equipped with
Michelson interferometers. Here, Matsuo et al.1 presented a new spectral imaging method for Fizeau
interferometers, based on double Fourier interferometry. They noticed that a delay axis in Michelson
interferometers is equal to the axis of a fringe pattern on an image plane in Fizeau interferometers.
Therefore, this new approach can acquire three-dimensional information of the sky using a linear array
detector placed on the image plane. In this paper, we compare the new spectral imaging method for
Fizeau interferometer with the conventional one used for Michelson interferometer and discuss spectral
resolutions and field of views of these imaging methods.
