Enhancement of Stellar Interferometry Systems
In fiber optics, combining light from several telescopes is still a challenge. Sensitivity of the interferometer depends on the scalability of large arrays of telescopes, overall beam combiner transmission, Visibility 2 Pixel Matrix conditioning, polarization and intrinsic chromatic dispersion of the beam combiner. In this project related to the field of stellar interferometry, the team had shown results for the experiments done with 4 or6 telescopes using DBC architecture. This was done to justify the need to perform research for the combination of more number of telescopes, and to measure the Signal to Noise ratio of the recovered fringe with the visibility amplitude of the target.
