摘要： A detection device provides a voice signal of a person and includes a light source, a first planar carrier medium, a second planar carrier medium, a sensor device, and an evaluation device. The first planar carrier medium includes an input coupling region and an output coupling region. The second planar carrier medium includes a light input coupling region and a light output coupling region. Light from the light source is emitted into the second planar carrier medium and output in the direction of a front neck region of the person, and the light reflected on the neck region is input into the first planar carrier medium and output out of the first planar carrier medium. The output light is detected by the sensor device which provides sensor data to the evaluation device which converts the sensor data into vibrational data and provides the voice signal.

摘要： A design screen and at least one detection device with an image capturing device and a carrier medium are provided in an external lighting device for a motor vehicle. The carrier medium is a flat waveguide on which a coupling region and a decoupling region are provided. The carrier medium is adapted to the surface shape of the design screen. The coupling region and the decoupling region are each a holographic element. Light incident on the external lighting device from the surroundings is coupled into the carrier medium via the coupling region, is transported to the decoupling region by internal reflection in the waveguide, and is decoupled at the decoupling region. The image capturing device detects the decoupled light and provides image data which correlates to the detected light.

摘要： A camera apparatus records only those objects in a surround which are situated in a predetermined object plane at a distance from the camera apparatus. To this end, the camera apparatus includes an illumination device for illuminating the desired object with an illumination light and an image capture device (for capturing the illumination light reflected by the object. For recording that is dependent on the object plane, the camera apparatus additionally comprises a control device for driving the illumination device to provide the illumination light in the form of light pulses and for controlling the image capture device to capture the reflected illumination light within recording intervals assigned to the light pulses. To avoid interference effects on a resultant image representation, provision is additionally made for a deflection unit for deflecting the respective illumination light between the surround and the illumination device and the image capture device.

摘要： A carrier medium embodied as a light guide has an input coupling region and an output coupling region, each of which are embodied as a holographic element. The carrier medium forms a cover plate for an image display region of a screen and the input coupling region is at least one partial region of the cover plate surface. Light incident on the input coupling region from the surroundings is coupled into the carrier medium, transmitted to the output coupling region by internal reflection and is in turn coupled out from the output coupling region. The coupled-out light is captured by an image capturing device and used to generate image data correlated with the captured light.

摘要： A 3D printing apparatus includes a synthetic resin bath for a photosensitive synthetic resin and a lifting apparatus. The photosensitive synthetic resin at the lifting apparatus is polymerizable by light of a specified wavelength. The 3D printing apparatus further includes a carrier medium having a coupling-in region and a coupling-out region, and an illumination apparatus to emit light onto the coupling-in region. The coupling-in region includes a coupling-in deflection structure to couple light of the specified wavelength incident on the coupling-in deflection structure from the illumination apparatus, into the carrier medium in a direction of the coupling-out region, and the coupling-out region is disposed below the synthetic resin bath and includes a coupling-out deflection structure configured to couple the light of the specified wavelength that is incident on the coupling-out deflection structure, as an exposure pattern, out of the carrier medium onto the photosensitive synthetic resin.

摘要： A method of operating virtual reality glasses in a vehicle, in which a risk of motion sickness for a wearer of the virtual reality glasses is reduced with the aid of the method. A virtual reality system (IO) includes the virtual reality glasses and the vehicle. According to the method, a vehicle movement of the vehicle is evaluated in such a way that ultimately, after the image data describing the virtual surroundings have been split into a background image dataset and a foreground image dataset, a lateral offset for a position of an object in the foreground in comparison with the background is determined, so that virtual surroundings which are processed in this way can be determined and displayed. Alternatively, the virtual surroundings can be enlarged in accordance with the vehicle movement, and processed virtual surroundings can be determined by a movement of the enlarged virtual surroundings along a movement trajectory, and displayed.

摘要： A carrier medium is designed as a waveguide on which a coupling region and a decoupling region are provided. The coupling region is designed to couple light, which has been emitted from a light source and reflected on an object in the surroundings, into the carrier medium. The coupled reflected light is then transmitted to the decoupling region by internal reflection, and the reflected light is decoupled again at the decoupling region and is transmitted to the at least one sensor device, which is designed as a time-of-flight camera device. The sensor device provides the detected light in the form of sensor data, describing the propagation time of the light reflected on the object, to an analysis device that obtains object data, which describes the position of the object.
