Device for projecting an image on a surface and device for moving said image |
摘要 |
The invention relates to a device for projecting an image on a surface, comprising: a light source generating a light beam; a mask arranged in the path of the light beam; a lens arranged behind the mask to focus the image of the mask on a surface, wherein the surface is not parallel to the lens, wherein at substantially each position along the edges of the mask the distance v to the lens and the distance b of the corresponding position at the edges of the image of the mask to the lens correspond substantially to the formula 1/v+1/b=1/f, wherein f is the focal length of the lengths. The invention also relates to a device for moving the image on the surface. |

1. A device for projecting an image on a surface, comprising:
a light source generating a light beam; a mask arranged in the path of the light beam; and a lens arranged behind the mask to focus the image of the mask on a surface, wherein the surface is not parallel to the lens wherein at substantially each position along the edges of the mask the distance v to the lens and the distance b of the corresponding position at the edges of the image of the mask to the lens correspond substantially to the formula 1/v+1/b=1/f, wherein f is the focal length of the lens, wherein the surface is the surface of an ablatable material and the light beam is a laser beam to generate a plasma plume of the ablatable material, wherein a substrate is arranged such that the surface of the substrate is coated with the ablatable material, and wherein the mask is a flat plate and the flat plate is arranged under an angle with the lens. |
