Method and apparatus for determining deformation and elongation on curved bodies

摘要

The present invention provides a method and associated apparatus with which it is possible to implement both shape detection and also displacement measurement in particular using partially identical working steps. A method according to the invention for determining the displacement of at least a part of the surface of a measurement object between an initial condition and a measurement condition and the shape of that surface of the measurement object is characterized in that the operation of determining the shape and the operation of determining the displacement are effected with the same measurement method using the speckle effect.
