  • Marking apparatus having feedback-controlled rotational laser beam
    Patent number: 5926305
    Abstract: A rotating laser apparatus having a reciprocating laser scanning system which facilitates visual recognition of a laser beam on an object to be measured by raising an effective energy level on the object. In the apparatus the laser beam is rotated by a rotation device. The reciprocating laser scanning system includes reflection members for reflecting the laser beam, a laser beam detector for detecting a return laser beam reflected from the reflection members, and a microcomputer for controlling a rotation of the rotation device in accordance with the output of the laser beam detector.
    Type: Grant
    Filed: June 9, 1997
    Date of Patent: July 20, 1999
    Assignee: Topcon Corporation
    Inventors: Fumio Ohtomo, Hiroyuki Nishizawa, Jun-ichi Kodaira, Kenichirou Yoshino
