Abstract
We report here a novel experimental scheme for the measurement of strain that utilizes a simple intensity based interrogation system through use of optical fibers. Corresponding to splicing of a multimode fiber between two single mode fibers, the transmittance was measured by subjecting them to strain at multi points. The measurements corresponding to those multi points are found to mimic multimode interference, considerably. The set-up has the potential to be applied in crack propagation analysis.
