  • Shadow-free 3D and 2D measurement system and method
    Patent number: 7340107
    Abstract: A shadow-free 3D and 2D measurement system combining, in one FMI set-up, a Moiré 3D lighting with other simultaneous external illuminations (for example a coaxial one or another). The reconstructed image combines the advantages of these different illuminations. The relative light intensities are selected in order to assure the best 2D detection while maintaining the 3D measurements.
    Type: Grant
    Filed: September 4, 2003
    Date of Patent: March 4, 2008
    Assignee: Sol Vision Inc.
    Inventors: Louis Berard, Michel Cantin, Alexandre Nikitine
  • Method and system for detecting defects on a printed circuit board
    Patent number: 6771807
    Abstract: A method and a system for detecting surface defects on electronic circuits, such as Printed Circuit Boards (PCB), are described herein. The method first comprises identifying contours on a digital image of the PCB. Then anomalies are detected on the PCB image by comparing the identified contours to contours on a vectorial model of the PCB. Each detected anomaly is compared to manufacturing data to verify if it corresponds to a defect.
