Electronically scanned optical-fiber Young's white-light interferometer.
An optical-fiber version of Young's interferometer that uses a low-coherent-light source and a linear chargecoupled-device detector is described. With its unique, simple structure, this interferometer greatly reduces the spatial coherence mismatch from which other electronically scanned white-light interferometers suffer. Experimental results are presented for the use of this interferometer as a strain or temperature sensor with a large dynamic range.
