Abstract
A system for measuring optical distortion in a contoured glass sheet includes a conveyor for conveying the glass sheet 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 glass sheet, and logic for performing one or more optical processing operations on the surface data to analyze the optical characteristics of the glass sheet.
