Disentanglement of mixed interference fringes in optical interferometers: theory and applications

Autor: Yang, Kaiyuan, Wei, Weilong, Ma, Xiafei, Chen, Botao, Chu, Junqiu, Liu, Xinling, Cheng, Yuhua, Yang, Hu, Ma, Haotong, Qi, Bo, Xie, Zongliang

Optical interferometric imaging enables astronomical observation at extremely high angular resolution. The necessary optical information for imaging, such as the optical path differences and visibilities, is easy to extract from fringes generated by
