Paper Abstract

Influence of laser spectra on a fiber optic Michelson interferometer's contrast is mathematically described and simulated. Proposal of using contrast-based setup as elongation meter as well as method of measuring range increasing and algorithm for signal processing is also presented. Experimental setup and software were worked out. We obtained 5-mm measuring range, where the biggest difference between real and measured elongation is 25 μm.
