  • Publication number: 20250108587
    Abstract: An arrangement, includes an illuminable pane having a first main surface and an opposite second main surface, an illuminating device for generating light, the illuminating device being configured such that at least part of the light generated by the illuminating device is incident on the first main surface in such a manner that it can pass the illuminable pane and leave the illuminable pane at the second main surface, a reflective structure arranged at the second main surface, provided with a plurality of reflective surfaces for the reflection of light, the reflective surfaces being in the form of inclined surfaces that are coated with a reflective layer, the reflective surfaces being configured such that at least part of the light leaving the second main surface can be reflected into the illuminable pane at such an angle that total reflection of the reflected light takes place in the illuminable pane.

  • Patent number: 12223584
    Abstract: A method for simulating the effects of the optical quality of windshield onto the image recording quality of a digital image recording device, in particular a digital image recording device for an advanced or automated driver-assistance system. The method is based on a combination of an adapted stochastic ray tracing method and of a convolutional image processing to simulate the effects of the optical distortions of a windshield on the image recording quality of a digital image recording device. The simulation is performed from a measured optical quality function of the windshields related to those optical distortions.
