  • Method of focusing optical apparatus
    Patent number: 4501962
    Abstract: Automatic focusing apparatus comprising a beam focusing assembly disposed for directing through an axially spaced focal spot a scanning light beam having a periodic translational movement characterized by a first fundamental frequency component, a focus evaluating assembly disposed for detecting adjacent the focal spot a periodic translational movement of the focused beam characterized by a fundamental frequency component which is compared with said first fundamental frequency component to determine the relative phase relationship, and a target positioning assembly disposed for automatically positioning a selected surface of a target at the focal spot in accordance with the periodic translational movement of the focused beam and said determination of relative phase relationship.
    Type: Grant
    Filed: May 9, 1983
    Date of Patent: February 26, 1985
    Assignee: Raytheon Company

  • Laser material removal apparatus
    Patent number: 3941973
    Abstract: A laser material removal apparatus and method of removing material from a workpiece wherein a laser forms a beam of radiation having a substantially circular cross-sectional configuration, and optical means is provided for compressing portions of the beam so that the resultant focused beam will provide an image of substantially rectangular shape and uniform energy whereby improved control of the size and shape of the area to be removed is obtained.
