In source detection in the Tianlai project,locating the interferometric fringe in visibility data accurately will influence downstream tasks drastically,such as physical parameter estimation and weak source exploratio...
Guo Shou Jing Telescope(the Large Sky Area Multi-Object Fiber Spectroscopic Telescope)is a National Major Scientific Project built by the Chinese Academy of Sciences.Funding for the project has been provided by the National Development and Reform Commission;supported by the National Key R&D Program of China(Grant Nos.2022YFA1603002,2022YFA1603001,2021YFC2801402 and SQ2021YFC2800011);the National Natural Science Foundation of China(Grant Nos.U2031207,U1931207,12073053,and 1331204)。
Co-phase and co-focus detection is one of the key technologies for large-aperture segmented mirror telescopes.In this paper,a new edge sensor based on fringes of equal thickness is developed,which can detect each segm...
