Abstract

Abstract:

The technique of absolute distance measurement with laser Frequency Scanning Interferometry （FSI） holds immense potential for various space science missions and aerospace engineering applications. However， the laser phase noise from the tunable light source significantly degrades the distance measurement resolution over long distances. To address this issue， this paper establishes an FSI absolute distance measurement system with a fiber optic reference interferometer. On this basis， a laser phase noise compensation method is proposed based on the hierarchical decomposition of interferometric signal noise phase error terms. The effectiveness of the proposed laser phase noise compensation method is validated through simulation and experiment. Simulation results demonstrate that at distances of 100 m， 200 m， and 500 m， employing the proposed method enhances the signal-to-noise ratio of the interferometric signal from -23.06 dB， -32.95 dB， -40.21 dB to 33.97 dB， 33.98 dB， and 33.97 dB， respectively， significantly improving distance resolution. Experimental distance measurement results indicate that with a measured fiber length of 114.887 m， utilizing the proposed method elevates the signal-to-noise ratio of the interferometric signal from -19.08 dB to -2.22 dB， resulting in a notable enhancement in distance resolution.

Key words: frequency-scanning interferometry, absolute distance measurement, phase extraction, tunable laser, laser phase noise compensation
