Abstract
Formation flying interferometry can increase the distance between satellites compared to ground-based interferometers. However, as the baseline length increases, longer observing time is required to fill the U-V plane. Here, focusing on the continuity of observation wavelengths from space, we develop a method to reconstruct spectra of diffuse objects only by rotating the baseline without changing the baseline length. The proposed method enables future space interferometry, such as the Large Interferometer for Exoplanets (LIFE), to spatially resolve distant objects and obtain their spectra.
