IR single-mode fiber optics for double Fourier interferometry.
Abstract
Double Fourier Interferometry (DFI) is one of the efficient ways to obtain simultaneously spatial and spectral information of the star in the IR range. In this paper, the authors investigate the possibility and limitation of using IR single mode fiber optics for DFI. Problems and effects, such as chromatic aberration of the Optical Path Difference scan, and hence the chromatic aberration of the truncation, unequal interval sampling effects, polarization effects, resulted from the OPD scan by stretching optical fibers are analyzed and discussed.
