We present low-coherence virtual reference interferometry (LC-VRI) for short length (<1 m) fiber dispersion characterization using a broadband LED source and a low-resolution spectrometer or spectrum analyzer. The LC-VRI is a simple and convenient alternative to balanced spectral interferometry (BSI), capable of measuring both first- and second-order dispersion directly from the interference pattern...
Using a broadband source, a slow detector, and a modulator, we propose and demonstrate a single-arm frequency-shifted interferometer capable of sensing multiple weak reflections simultaneously in parallel and in series at 0.1-m spatial resolution.
We use frequency-shifted interferometry to detect the concentrations of the same gas species at different locations and in different mixtures by accurately correcting the spectral shadowing effect. Different gas species are also detected.
