Abstract: A system for measuring reflected optical distortion in a contoured panel having a specular surface includes a conveyor for conveying the panel in a first direction, at least one display projecting a preselected multi-phase non-repeating contrasting pattern, and at least one camera, each one of the cameras uniquely paired with one of the displays. The system may also include a control programmed to execute logic for controlling each of the cameras to acquire the desired images, and logic for analyzing and combining the data acquired by the cameras to construct a definition of the surface of the panel, and logic for performing one or more optical processing operations on the surface data to analyze the optical characteristics of the panel.

Abstract: A system and method for gaging the shape of a curved glass sheet includes, as components, (1) a system and method for acquiring three-dimensional surface data corresponding to the glass sheet, and (2) a system and method for receiving the acquired surface data, comparing the acquired surface to a pre-defined surface description, and developing indicia of the level of conformance of the contoured glass sheet to the pre-defined specification. The surface data acquisition system includes a conveyor for conveying the glass sheet, at least one display projecting a preselected contrasting pattern, and at least one camera. The camera(s) and display(s) are uniquely paired and are mounted in a spaced-apart relationship a known distance and angle from the surface of the glass sheet such that the camera detects the reflected image of the pattern projected on the surface of the glass sheet from its associated display.

Abstract: An optical inspection system is provided with a fixture to support a glass sheet, with the fixture having an optical fiducial. An ultraviolet laser and associated optics form a planar laser sheet that intersects a surface of the glass sheet causing the surface to fluoresce and form a visible wavelength line thereon. A camera has an image sensor for detecting the optical fiducial and the visible wavelength line across at least a portion of a width of the sheet. A control system is configured to (i) image the optical fiducial on the fixture, (ii) define an optical fiducial coordinate system from the imaged optical fiducial, (ii) receive a mathematical model of the glass sheet in a model coordinate system, and (iii) relate the optical fiducial coordinate system to the model coordinate system via at least one transformation. A method of using a non-contact optical inspection system is also provided.

Abstract: A small defect detection apparatus installed online in a glass sheet processing system includes a line scan camera, a background screen including contrasting elements arranged in a pre-defined pattern, an upstream conveyor and a downstream conveyor, wherein the upstream conveyor and downstream conveyor are positioned end-to-end, spaced apart by a selected size gap such that the camera may acquire multiple images of the background screen as the unsupported portion of the glass sheet is conveyed over the gap, and a computer programmed to execute logic for receiving the set of image data comprising multiple images of the background screen and identifying small defects in the glass from the data. The system may also include a glass sheet part identifier and a programmable control including logic for analyzing acquired image data and selecting an area of interest on the glass sheet for the analysis.

Abstract: An optical inspection system is provided for an ultraviolet laser and associated optics forming a planar laser sheet directed to a glass sheet. The planar laser sheet intersects a surface of the glass sheet thereby causing the surface of the glass sheet to fluoresce and form a visible wavelength line on the surface. A camera has an image sensor for detecting the visible wavelength line. A control system in configured to receive image data indicative of the visible wavelength line, analyze and triangulate the data to determine a series of coordinates associated with the line, and create a three-dimensional map of the surface of the glass sheet as a function of the series of coordinates. Methods for using an optical inspection system, for gauging a surface using an optical inspection system, and for providing optical reflectance information for a surface using an optical inspection system are also provided.
