20140340655 | PROJECTOR, AND METHOD FOR CONTROLLING A PROJECTOR ACCORDING TO THE INVENTION - A projector having at least one laser diode which is designed to emit light, having a laser control device which is designed to control the at least one laser diode, having a first controllable resonant mirror which is designed to reflect the light that is emitted by the laser diode, and having a control device which is designed to control the orientation of the first controllable resonant mirror. The control device is further designed to reduce the power supply to the laser diode and to the laser control device in a first configuration of a power-saving mode of the projector, and to further control the orientation of the first controllable resonant mirror at a resonant frequency of the first controllable resonant mirror. Moreover, a corresponding method is described. | 11-20-2014 |

20100135462 | PRIMARY COLLIMATOR AND SYSTEMS FOR X-RAY DIFFRACTION IMAGING, AND METHOD FOR FABRICATING A PRIMARY COLLIMATOR - A primary collimator for a multiple inverse fan beam x-ray diffraction imaging (MIFB XDI) system. The MIFB XDI system includes a multi-focus x-ray source (MFXS) defining a plurality of focus points arranged along a length of the MFXS. Each focus point is sequentially activated to emit an x-ray fan beam including a plurality of primary beams each directed to a corresponding convergence point. The primary collimator includes a first diaphragm configured to be positioned with respect to the MFXS. The first diaphragm defines a plurality of first channels through a thickness of the first diaphragm. Each first channel is aligned with a corresponding focus point and configured to transmit the x-ray fan beam. A second diaphragm is positioned with respect to the first diaphragm and defines a plurality of second channels through a thickness of the second diaphragm. Each second channel is axially aligned with a corresponding first channel. | 06-03-2010 |
