The use of moiré topography in study of a form a pump blade

Original language description

To study a form of a space object of large dimensions and depth, the optical moiré topography can by used as one of the advisable non-contact measuring methods. The moiré pattern can by realized by projection of a grating from two directions on a studiedobject. The resulting moiré pattern is a contour line system showing equal depth from any fundamental plane, if the light sources lie on a plane parallel to this fundamental plane. CCD video-camera and Fast Fourier Transform allows improving of the viedeo-signal and corresponding moiré topographical image. This better visualization of moiré pattern enables adjustment of the TV signal for its computer processing. Obtained contour line system can be considered as a map describing in high precision the space form of a testing object.
