This study introduces a phase alignment method for array optical telescopes using balanced detection. The technique effectively compensates for phase deviations, significantly improving communication reliability and reducing bit error rates in turbulent conditions.

Area of Science:

  • Optical Engineering
  • Signal Processing
  • Atmospheric Optics

Background:

  • Atmospheric turbulence causes light spot issues like flickering and deviation in optical systems.
  • Coherent beam combination in array receivers faces challenges in detecting and compensating for sub-aperture phase deviations.

Purpose of the Study:

  • To propose and demonstrate a phase alignment method for array optical telescope systems using balanced detection.
  • To address the challenge of phase deviation compensation in coherent beam combination.

Main Methods:

  • Utilized an improved Mach Zehnder Interferometer (MZI) for simultaneous digital signal demodulation and phase difference recovery.
  • Employed balanced detection for phase alignment in an array optical telescope system.
  • Conducted simulations using OptiSystem and MATLAB to validate the proposed method.

Main Results:

  • The proposed method achieved a 3 dB receiver gain and enhanced detection sensitivity.
  • Simulations showed power values near the ideal 2.75 mW and bit error rates below 10-9 post-compensation.
  • Reduced bit error rate from 1 to 10-35 for a 90-degree communication interruption, re-establishing communication.

Conclusions:

  • The balanced detection method is effective and accurate for phase alignment in array optical telescope systems.
  • The improved MZI enhances system performance by demodulating signals and recovering phase differences.
  • The technique significantly improves communication reliability under atmospheric turbulence.
