Abstract
A device for imaging of modulated light onto a thermally sensitive medium having lens means which can image the beam cross-section of the light beam which emerges from a modulator plane onto the surface of the thermally sensitive medium. The lens means is made such that the cross-section of the light beam emerging from the modulator plane can be imaged in the first direction (x) more dramatically enlarged, or more weakly reduced, onto the surface than in the second direction (y), and at least for the duration of irradiation of the surface of the thermally sensitive medium with the light beam imaged by the lens means, the surface can be moved in the second direction (y).

A device for imaging of modulated light onto a thermally sensitive medium, comprising:
- a lens means which images a beam cross-section of a light beam which emerges from a modulator plane onto a surface of a thermally sensitive medium, wherein the lens means are made such that the beam cross-section which emerges from the modulator plane can be imaged in a first direction (x) more dramatically enlarged, or more weakly reduced, onto the surface of the thermally sensitive medium than in a second direction (y), and at least for a duration of irradiation of the surface of the thermally sensitive medium with an imaged light beam imaged by the lens means, the surface can be moved in the second direction (y).
