Enhancement of Stellar Interferometry Systems

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.

Algorithms/Methods Implemented:

  1. Simulation of  ABCD, DBC and 2 other interferometers
  2. Design the  interferometer based on best coupled waveguide configuration
  3. Waveguide configurations and their modelling with complete mathematical analysis
  4. Performance comparison with increase of telescopes for Fizaeu interferometer and Michelson interferometer
  5. Design and simulation of a beam combiner

Technologies/Software:

  1. MATLAB
  2. RSOFT
  3. Finesse
  4. Labview
  5. Simulink
