Astronomy
A telescope as wide as its baseline
Separate two telescopes and resolve a double source through changing fringe visibility. Compare angular resolution with the fringe contrast.
The model and its limits
Two identical unresolved sources of equal brightness and a monochromatic two-element interferometer. No aperture synthesis, atmosphere or bandwidth smearing.
Equations used in the module
Equations V = |cos(πBθ/λ)|; C = cos(πBθ/λ); I = 1+C cos φ; resolution scale = λ/B
