High-Precision Optical Time Delay Measurement Based on Carrier-Suppressed Optical Double-Sideband Modulation

We propose a high-precision optical time delay measurement method based on carrier-suppressed optical double-sideband (ODSB) modulation, which features high accuracy and stability. In the experiment, a high-precise motorized variable optical delay line is precisely measured.
