ABSTRACT:
An apparatus and method for recording an image on the surface of a 3D object uses a laser projector that scans a light beam over the surface in an image pattern. The projector operates in a template imaging mode and an image recording mode where the beam scans at a speed that in a single pass/scan mode is typically four to five orders of magnitude slower than in the template imaging mode. A layer of a photosensitive material is applied to the surface of the object either partially or fully. Projection in the template imaging mode can guide the applying. The layer is substantially insensitive to ambient light for at least a period of time necessary to perform a desired processing step on the object. The layer has a maximum spectral sensitivity in the vicinity of the wavelength of the laser light beam. In one or multiple passes of the beam over the image pattern operating in the image record mode, the accumulated light energy dose density is sufficient to react the material and record the image.
