Patents by Inventor George M. Jewett

George M. Jewett has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6670576
    Abstract: The method for producing images inside transparent materials by combination of laser-induced color centers and laser-induced damages is disclosed. The method is based on two physical phenomenon: photoionization and laser-induced breakdown. The method includes transformation of the computer image into arrangements of pixels, which should be produced as either areas of laser-induced color centers or laser-induced damages inside transparent materials. The same laser produces both color centers and laser-induced damages by controlling the energy of generated pulses. The method enables to produce several different laser-induced images inside the same transparent material so that each of them is visible inside its small space angle.

  • Patent number: 6630644
    Abstract: A method for creating arrangement of damages for production of 3D laser-induced damage portraits with the space resolution, which is equal to the appropriate computer 3D model, is disclosed. 3D laser-induced damage portraits produced by the method, have sufficiently tight faces and profiles so that the clearance surface dose not interfere the face surface, and the right (left) profile does not interfere with the left (right) profile. These effects are created by production of the sophisticated arrangement of damages, placed both on 3D portrait surface and inside area of the 3D portrait. Due to the method it is possible to make laser-induced damages, corresponding to all pixels of the 3D computer model and reproduced the right brightness of the material point without the internal split.
