Implication

Experimental study demonstrates refractivity-corrected distance measurement over 50 meters using supercontinuum beats, highlighting its potential for long-distance metrology.

Key Points

Refractivity-corrected distance measurement resolves atmospheric dispersion errors, enabling high-precision optical tracking through intermode beats.
Standard deviations reach around 0.08 mm during optical path length changes, while baseline measurement residuals stay near 0.1 ppm across distances.
Two-color method measurements demonstrate inline refractivity compensation, highlighting strong potential for practical long-distance optical metrology.
