Patents by Inventor Juergen Ernst

Juergen Ernst 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).

  • Measurement of a fiber direction of a carbon fiber material and fabrication of an object in carbon fiber composite technique
    Patent number: 9234836
    Abstract: The fiber direction of a carbon fiber material of a test object is detected by means of the polarization direction of light reflected by the test object. If, for example, non-polarized light impinges upon carbon fibers, light reflected by the fibers is polarized in fiber direction.
    Type: Grant

    Inventors: Juergen Ernst, Stephan Junger, Wladimir Tschekalinskij
  • Optical aliasing filter, pixel sensor arrangement and digital recording device
    Patent number: 8593562
    Abstract: A refraction at a suitably structured surface for example with an arrangement of the same between image plane and mapping optics is used to realize on the one hand a desired aliasing filtering or spatial low-pass filtering on the image plane wherein on the other hand the manufacturing of such structured surfaces may be realized in a cost-effective way. In addition to that, the plate thickness except for the amplitude of the surface structure and aspects of the stability of the plate is of no importance for handling the same, so that the integration into optical systems is facilitated.
