Summary:The present disclosure relates to the field of measuring the three-dimensional shape of 3D structures, particularly wind turbine structures such as wind turbine blades, using fiber optic strain sensors (i.e., fiber Bragg gratings, FBGs). Disclosed is a device and a corresponding method for measuring the three-dimensional shape of a structure by being slidably coupled to the structure such that a deformation of the structure other than elongation or shortening causes a corresponding deformation of the device, the device comprising: a flexible beam; three or more optical fibers arranged longitudinally parallel within the beam and having a lateral distance between the optical fibers in at least two different lateral directions; wherein the optical fiber comprises a plurality of sensor areas distributed along the optical fiber, and in each optical fiber, each sensor area comprises a fiber bragg grating. 本公开涉及使用光纤应变传感器(即光纤布拉格光栅，FBG)来测量3D结构(具体地如风力机叶片的风力机结构)的三维形状的领域。公开了一种用于测量结构的三维形状的装置和相应的方法，该装置通过可滑动地联接至该结构使得该结构的除了伸
