Area of Science:

• Aerospace Engineering
• Optical Physics
• Photonics

Background:

• High-speed aircraft maneuvers require precise, high-frame-rate distance measurements.
• Existing optical ranging technologies (dual-station triangulation, laser rangefinders) have limitations in speed, complexity, cost, or repetition rate.

Purpose of the Study:

• To present and validate a kilohertz-level single-photon ranging system for aircraft applications.
• To assess the system's performance in capturing relative distance, velocity, and acceleration during high-speed maneuvers.

Main Methods:

• Development of a single-photon ranging system utilizing high-frequency, low-energy pulses and single-photon detection.
• Field testing of the system in civil aviation scenarios.
• Analysis of measurement reproducibility by simulating lower frame rates through misalignment merging.

Main Results:

• Successful capture of relative distance, velocity, and acceleration at 1000 Hz.
• Demonstrated improvement in distance measurement reproducibility with higher frame rates (lower standard deviations at 1000 Hz compared to simulated 100 Hz, 50 Hz, 10 Hz).
• Error analysis confirmed enhanced precision for high-speed maneuver monitoring at high frame rates.

Conclusions:

• Kilohertz-level single-photon ranging is a viable and precise method for characterizing high-speed aircraft maneuvers.
• Higher frame rates significantly improve the reproducibility and precision of distance measurements in dynamic scenarios.
• This technology offers a promising alternative to existing ranging methods for aviation applications.
