  • Method for scanning a laser beam by non-mechanical deflectors
    Patent number: 4925261
    Abstract: A method for making an image line (10) with a laser beam, according to whichthe laser beam is created by a laser (1)the intensity of the laser beam is modulated by an external modulator or by said laser (1)said modulated laser beam is fed into a coding element (2,3), by means of which at least one of the properties of the laser beam is transformed, e.g. amplitude, phase or direction, using an electrical control signalthe coded laser beam is fed into the hologram (9), by means of which the laser beam is transformed into focused image spots (20 . . . 24a,b,c)from said image spots (20 . . . 24a,b,c) an image line (10) is formed on the image plane andsaid laser beam is guided and transformed by optical elements.
