The effects of finite telescope pupil sizes on the measurement of fringe visibility in fiber optic stellar interferometry are described. It is shown theoretically that the measured fringe visibility is equal to the cross correlation of the magnitude of the source’s mutual coherence function with the cross correlation of the telescopes’ effective pupil functions. If the telescopes’ effective pupil diameters are not small compared with the width of the source’s mutual coherence function, then the measured fringe visibility will be correspondingly distorted. The theoretical results are verified experimentally in a fiber optic Mach–Zehnder interferometer.
