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.

A spectrometry device includes a carrier medium, or waveguide, for transmitting light by internal reflection, and a transceiver device that has at least one light source and a detection device. A transceiver deflection structure couples at least the light emitted by the light source into the carrier medium. A measurement deflection structure, arranged at a distance from the transceiver deflection structure, decouples the light out of the carrier medium onto a measuring surface of the carrier medium so that the biological tissue can reflect the light back to the carrier medium. The reflected light is transmitted back onto the detection device via the measurement deflection structure, the carrier medium and the transceiver deflection structure. The detection device determines an intensity signal of the reflected light which is used by an analysis device to determine a pulse frequency signal and/or a pulse curve signal as a medical characteristic value.

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.

A camera apparatus includes a flexible carrier medium formed as a light guide and on which an input coupling region and an output region are disposed. Light, which is incident on the input coupling region from the surroundings, can be input into the carrier medium via the input coupling region. Internal reflection allows the light to be transmitted through the carrier medium from the input coupling region to the output coupling region. At the output coupling region, the transmitted light can be output from the carrier medium and be captured by an image capture device, which is disposed adjacent to the output coupling region.

Cost-effective, spatially representative image data is recording in a stereoscopic or photogrammetric image of an environment by a camera apparatus having three holographic-optical elements arranged as coupling regions at different positions on a carrier medium to capture the environment from different perspectives. Light from the environment is coupled by the coupling regions into the carrier medium which provides a light guide that transfers the light to an additional holographic-optical element which provides a decoupling region to decouple the light from the carrier medium. An image capture device captures the decoupled light and produces image data therefrom. A separating device produces the spatially representative image data from the image data by capturing the light incident on the coupling regions in a manner separated temporally or by color.
