|Issue Date:||1997||Publisher:||Elsevier||Source:||Optics Communications,1997, Volume 134, Issue 1-6,Pages 341-348||Abstract:||We describe an all-fibre, passive scheme for making extended range interferometric measurements based on the dual wavelength technique. The coherence tuned interferometer network is illuminated with a single superfluorescent fibre source at 1.55 μm and the two wavelengths are synthesised at the output by means of chirped fibre Bragg gratings. We demonstrate an unambiguous sensing range of 270 μm, with a dynamic range of 2.7 × 105||URI:||http://ktisis.cut.ac.cy/handle/10488/7396
