Abstract
A double-polarization interferometer with digital readout by fringe counting allows for discrimination between strain applied to the 'reference'- and 'signal'-arm respectively under transverse force induced fiber tension bending. This is utilized for laterally resolved displacement sensing by employing an array of interferometer arms placed under an elastic skin. Experimental results of the one-dimensional field of strain-displacement characteristics employing the four parallel arms of two Michelson interferometers are compared with the theoretically expected, to first order quadratic dependence of strain on displacement under transverse force.
