In order to measure deformation of wing structure, points of interest are photographed on moving strip of sensitized paper; these points are either marked by lamp or mirror; changing deformations, particularly oscillations can be measured without inertia effect in instruments; sketches illustrate design of optograph; practical examples are given.
