Abstract
Process and apparatus for regulating the impact on a target of a light beam emitted by a source. The position and dimension of the impact are regulated by respectively using two beams, whose optical paths are coaxial. The apparatus comprises a target support and means for displacing it in its plane, means for focusing the light beam of the source on the target, means for regulating said focusing means, means for emitting a regulating light beam in the direction of the target, the location and dimensions of the impact of said regulating beam on the target corresponding to the predetermined location and dimensions of the impact of the light beam of the source, as well as optical visual display means for locating and regulating the dimension of the impact of the regulating beam, wherein the means for emitting the regulating beam and the visual display means for the impact position of the regulating beam on the target are independent of the means for focusing the light beam of the source, the optical paths of the light beam of the source and the visual display means for the impact position being coaxial and the optical paths for the visual display means for regulating the impact dimensions and the light beam of the source partly coincide.
