Abstract

We report a technique for temperature-insensitive strain measurement by broad-band interferometry. Changes in group delay and dispersion in a Mach-Zehnder interferometer are measured by dispersive Fourier transform spectroscopy (DFTS). These measurements give values for strain and temperature via a well-conditioned matrix transformation, so that strain measurements are independent of temperature change. The technique can be used for remote interrogation of sensors by tandem interferometry.
