    Abstract: An image displaying device includes a micro-LED-array having several LEDs, a controller electrically connected to the micro-LED-array for driving the LEDs such that they emit light, and a lens-array having several lenses. Each lens is assigned to one of the LEDs. Each lens is arranged in the light path of the light emitted by the corresponding LED such that the light emitted by the LEDs passes through the corresponding lens and is projected onto a screen. The lens-array is configured such that, when seen from the screen, a virtual image of the micro-LED-array is formed behind the micro-LED-array. The lens-array is a meta-lens-array and the lenses are meta-lenses.

    Abstract: A headlight includes a first LED cluster having a plurality of first LEDs arranged next to one another on a common first substrate, a second LED cluster having a plurality of second LEDs arranged next to one another on a common second substrate, and an output coupling optical unit having a plurality of optical elements, of which an optical element which comes first in a beam path of the LED clusters has, a light incidence surface which is common to the LED clusters. The LED clusters have a lateral distance from one another which is at least as great as an extent of the LED clusters in the same direction. The common light incidence surface has a locally delimited light incidence region directly in front of an associated LED cluster. The locally delimited light incidence region deviates from the basic shape of the light incidence surface.

    Abstract: A TOF camera for determining a distance to an object comprising: a radiation source configured to emit electromagnetic radiation toward the object, radiation-sensitive sensor elements configured and arranged to detect the electromagnetic radiation reflected/scattered by the object, an optical element arranged to influence the emitted electromagnetic radiation in the radiation path of the reflected/scattered electromagnetic radiation between the object and the sensor elements, a computing unit electrically connected to the radiation source and sensor elements configured to determine a time duration required by the electromagnetic radiation from the radiation source to the object; from the object to the sensor elements; and to determine the distance between the TOF camera and the object depending on the time duration determined. The sensor elements and/or the optical element are configured such that different sensor elements detect the reflected/scattered electromagnetic radiation from different solid angles on the far side of the optical element.
