Improving the precision and efficiency of an optical telescope array by the piecemeal method

Area of Science:

• Optical astronomy
• Astrometry
• Remote sensing

Background:

• Angular localization of remote optical objects is crucial for fields like astrometry and remote sensing.
• Existing telescope array methods face limitations in precision and efficiency.

Purpose of the Study:

• To introduce a novel "piecemeal method" for angular localization using telescope arrays.
• To demonstrate the method's advantages in precision, efficiency, and robustness.

Main Methods:

• Development of explicit formulas for the piecemeal method.
• Numerical simulations to validate the method's performance.
• Presentation of a reference-object-based implementation framework compatible with existing systems.

Main Results:

• Achieved a 10^4 improvement in precision with a 10^5 photon reduction compared to existing arrays.
• Outperformed the Gaia telescope by 10^3 and the quantum limit by 10^2 in precision.
• Demonstrated seamless integration with current optical interferometric systems.

Conclusions:

• The piecemeal method offers superior precision, efficiency, and robustness for angular localization.
• This advancement has significant implications for remote sensing and astrometry.
• The proposed framework facilitates practical implementation in existing astronomical infrastructure.
