Correction Method of Phase Deference in Accordance with the Angle Field for Wide-Viewing-Angle Fourier-Spectroscopic-Imaging

We are aiming at the realization of the wide-field imaging, such as the global greenhouse gas, by mounting the imaging-type 2-dimensional Fourier-spectroscopy into the earth observatory satellites. The proposed method is the spectroscopic imaging method based on the phase-shift-interference phenomena between objective beams. Spectrum will be deteriorated by the angle field in accordance with the viewpoints to realize the wide-field imaging. Thus, we proposed the phase-difference correction method to secure the accuracy of spectrum in whole imaging area. In this report, we constructed the geometrical correction model and verified the effectiveness for improving the spectrum of the whole imaging area.
