Abstract

A procedure is developed for mapping strain sensor readings into displacements. Optimal sensor layouts are determined by examining predicted mode shapes from synthesized strain data. The singular values of the transformation matrix bound the error in the inferred displacements. Issues of spatial aliasing as well as sensor spacing are also addressed. The methodology was validated by comparing both static and dynamic shape estimations with experiments.
