Abstract: A method for detecting inconsistencies in an assembly using an energy source and an imaging device is disclosed. An energy source directs energy through first scanning mirrors toward a surface of the laminated composite assembly raising an energy level of an inspection area. An imaging device directs a view through second scanning mirrors toward the inspection area and the imaging device detects a rate of change in energy at the surface of the laminated composite. Movement of the first scanning mirrors is synchronized with movement of the second scanning mirrors for directing a view of the imaging device to the inspection area after the energy level of the area of the surface has been raised. The imaging device detects dissipation of energy at the area of the surface being inspected and identifies inconsistencies associated defects in the assembly.

Abstract: A method of detecting a presence of foreign material in a ply is disclosed. A source of foreign material is marked with a fluorescent indicator. The source of foreign material is separated from the ply. An illumination source is provided for illuminating the ply at a different wavelength than the fluorescent indicator fluoresces so that the ply reflects light at a different wavelength. A sensor detects illumination of the ply and fluorescent indicator included in the foreign material disposed upon the ply. Differences in light reflected from the ply and fluorescence of the indicator disposed in the foreign material are detected thereby identifying existence of the foreign material in the ply.

Abstract: A rotary stage assembly includes a platform and a rotary drive defining an axis of rotation. The platform is mounted on a spindle for receiving rotary movement from the rotary drive. A cylindrical wall is attached to the platform receiving rotary movement from the rotary drive and is coaxial with the axis of rotation defined by the rotary drive. The cylindrical wall defines an inner surface including reference patterns. An imaging assembly images the reference patterns on the inner surface of the cylindrical wall. The imaging assembly detects angular orientation and tilt of the platform from an axis of rotation of the platform from imaging the reference patterns on the inner surface of the cylindrical wall. A controller calculates angular orientation and tilt of the platform from the location of said reference patterns signaled from the imaging assembly.

Abstract: A laser projection system for projecting an image on a workpiece includes a photogrammetry assembly and a laser projector, each communicating with a computer. The photogrammetry assembly includes a first camera for scanning the workpiece, and the laser projector projects a laser image to arbitrary locations. Light is conveyed from the direction of the workpiece to the photogrammetry assembly. The photogrammetry assembly signals the coordinates light conveyed toward the photogrammetry assembly to the computer with the computer being programmable for determining a geometric location of the laser image. The computer establishes a geometric correlation between the photogrammetry assembly, the laser projector, and the workpiece for realigning the laser image to a corrected geometric location relative to the workpiece.

Abstract: A method for validating the placement of pieces in an assembly task by scanning a coherent light source, such as a laser, over a surface and characterizing the detected interference speckle pattern to discriminate the position of the placed piece from the surface on which the piece is placed. This discrimination is possible even if the characteristic features of the piece and background are smaller than the resolution of the scanning system. In addition, characteristics of the piece, such as the orientation of fibers in the material, may be sensed by classification of the associated speckle response.

Abstract: A method and apparatus for verifying location and orientation of a piece attached to a work surface for s manufacturing a workpiece is disclosed. A controller is programmed with design data for manufacturing steps. Multiple layers of ply are sequentially layered over a work surface. An imaging system capable of redirecting a field of view along the work surface is provided. A light projector is provided for projecting reference features onto the work surface. The light projector projects a reference feature to a known location relative to the piece applied to the work surface within the field of view of the imaging device. The imaging device generates an image of the reference features projected by the light projector and of the piece applied onto the work surface. The controller compares the location of the piece on the work surface with the design data validating accurate placement of the piece.

Abstract: A method for aligning a laser projector for projecting a laser image onto a work surface is provided. The method includes providing a laser projector assembly with a laser source for projecting a laser image onto a work surface, a secondary light source for illuminating the work surface and a photogrammetry device for generating an image of the work surface. The method also includes affixing reflective targets onto the work surface and transmitting light from the secondary light source toward the work surface and reflecting light toward the photogrammetry device. The method further includes scanning the targets with a laser beam generated by the laser source for reflecting the laser beam toward a laser sensor and calculating a location for projecting the laser image onto the work surface from the reflected laser beam.
