Development of the imaging-type 2D Fourier spectroscopy into Infrared radiation region

Abstract

We proposed the imaging-type 2D Fourier spectroscopy that is a kind of the phase-shift interferometry between the objective lights without the reference lights. The proposed method can realize the 2D spectral imaging at the limited depth with high spatial resolution. In this report, we discuss about the long-stroke phase shifter whose position and attitude can be controlled from the displacement of the fringes of equal inclination to maintain the imaging quality.
