  • Method and apparatus for the fine position adjustment of a laser beam
    Patent number: 4713537
    Abstract: On an essentially non-absorbing plate located in the focal plane of a laser beam to be adjusted, a plurality of marks is arranged in a definite pattern. The marks deflect the laser light incident upon them by refraction, scattering, diffraction or otherwise, and direct the deflected light onto one or several laser detectors. The detectors convert the light received into corresponding electrical signals which may used for the fine adjustment of the laser beam by an evaluating electronic device.
