Paper Abstract

A static tandem Michelson interferometer configuration is reported for remote measurements of group delay change in a thermally modulated, optically dispersive BK7 glass sample. Using a superluminescent diode (SLD) to illuminate the interferometer, low-coherence measurement interferograms with signal-to-noise ratios as low as 16 dB were captured and subsequently processed using dispersive Fourier transform spectrometry (DFTS). Measurements of thermallyinduced delay change were made with < 2 fs root mean square error for optical path delay scans lengths of only 260 μm.
