  • Projection apparatus for scanningly projection
    Patent number: 7847997
    Abstract: A projection apparatus for scanningly projecting an image onto an image field by means of a radiation beam includes a modulator for modulating an intensity of the radiation beam such that the intensity of the radiation beam changes in a time interval during which a scan point to which the radiation beam is directed sweeps a pixel of the image field.
    Type: Grant
    Filed: February 27, 2008
    Date of Patent: December 7, 2010
    Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.

  • Projection apparatus
    Patent number: 6843568
    Abstract: The present invention is based on the finding that the previous column and row representation in the scanning image projection has to be given up, in order to enable that the ratio between row and column frequency or vertical and horizontal deflection frequency is not critical and may be decreased. An inventive projection apparatus for projecting an image on an image field includes a deflection means for deflecting a light beam about a first deflection axis at a first deflection frequency and about a second deflection axis at a second deflection frequency different from the first, in order to move the light beam across the image field, as well as a modulation means for modulating an intensity of the light beam depending on the image to be projected. The first and second deflection frequencies differ by less than an order of magnitude.
