This paper presents a method for estimating the shape of flexible structures from multipoint spatially distributed measurements of structural deflections. The estimation algorithm is based on an infinite-dimensional approach, where the estimation errors are reduced by introducing the necessary finite element truncation and approximation after solving the estimation problem for the distributed parameter system. This paper also proposes a remote optical sensing system for fast and precise measurements of multipoint structural deflections. The optical measurement system consists of a laser slit scanner and corner-cube reflectors distributed on the flexible structure. An experimental measurement system has been implemented for one-dimensional deflection estimation and tested on a simple structure in the laboratory. The results of the numerical simulations and experiments show the practical usefulness of the proposed shape estimation method.
