Fixed and variable resolution video moire techniques have been used to project structured illumination in a model undersea environment and a prototype system has been developed which generates equal depth contours of undersea objects and has applicat

Video technology is applied to the problem of moire metrology. In the past, moire metrology seemed a promising yet limited method in the measurement and comparison of surface shape. The use of video technology has widened the area of application of m

A common problem in fabrication and welding of complex structures is that there is no simple way to determine where to cut one part so that it will fit another part unless both parts designed and built on a CAD/CAM system. Particularly in prototype o

Several methods for generation of three dimensional surface shapes from variable resolution video moire contours are described. In a classical moire system, a physical grating is projected on a target and also used to view the target. The moire conto

Moire techniques can be a powerful tool to determine deviation of a manufactured shape from a desired shape. In a traditional moire system, distorted gratings on an object are viewed through an undistorted grating. The moire contours that result repr

Moire techniques can be a powerful tool to determine surface shape or deviation of a shape in progress from a final or desired shape. The presence of the high contrast viewing grating and the distorted grating of the final image plane makes the moire

The development of efficient high speed techniques to recognize, locate, and quantify damage is vitally important for successful automated inspection systems such as ones used for the inspection of undersea pipelines. Two critical problems must be so

A moire profilometry method has been developed that is capable of inspecting objects whose size is limited only by the available laser power. The moire contours are generated in real time by projecting variable spacing gratings upon the target and fi
