Finite telescope pupil sizes distort fringe visibility measurements in fiber optic stellar interferometry. This occurs when pupil diameters are comparable to the source

Area of Science:

  • Astronomy
  • Optical Engineering
  • Physics

Background:

  • Fiber optic stellar interferometry enables high-resolution astronomical observations.
  • Accurate measurement of fringe visibility is crucial for interpreting interferometric data.
  • Telescope pupil size is a key parameter influencing optical measurements.

Purpose of the Study:

  • To theoretically describe and experimentally verify the impact of finite telescope pupil sizes on fringe visibility measurements.
  • To establish the relationship between pupil size, source coherence, and measured fringe visibility.

Main Methods:

  • Theoretical analysis using the mutual coherence function and pupil functions.
  • Experimental verification using a fiber optic Mach-Zehnder interferometer.

Main Results:

  • Measured fringe visibility equals the cross-correlation of the source's mutual coherence function magnitude and the telescopes' pupil functions.
  • Significant distortion of measured fringe visibility occurs when telescope pupil diameters are not small relative to the source's mutual coherence function width.
  • Experimental results confirm the theoretical predictions.

Conclusions:

  • Finite telescope pupil size is a critical factor affecting fringe visibility measurements in fiber optic stellar interferometry.
  • Understanding this effect is essential for accurate astronomical data interpretation.
  • The study provides a theoretical framework and experimental validation for this phenomenon.
