摘要： TOF distance sensor for capturing the distance to an object by receiving radiation reflected by the object, said radiation emanating from a radiation source modulated by a modulation frequency, comprising a pixel matrix for recording a pixel image. The pixel matrix consists of demodulation pixels which are designed for rear-side reception of the radiation. The demodulation pixels comprise a conversion region for generating charge carriers from the received radiation, and a separating device for separating the charge carriers in accordance with the modulation frequency, and also a stop for partitioning-off the conversion region from the separating device in relation to the charge carriers, and also an aperture for passing the charge carriers from the conversion region into the separating device. The TOF distance sensor is embodied in such a way that in each case at least two demodulation pixels form a common aperture.

摘要： An optoelectronic device comprises a light processing device that, in turn, comprises at least one light sensor, the light processing device further comprising a device through-opening. The optoelectronic device further comprises a light source supported by a light source carrier adjacent to but not in direct contact with the light processing device, the light source configured to align with the device through-opening in the light processing device such that light emitted by the light source emerges from the device through-opening. The light processing device may comprise one or more first connection elements and the light source carrier may comprise one or more second connection elements corresponding to the first connection elements, the light processing device being operatively connected to the light source carrier via the first connection elements and the corresponding second connection elements.

摘要： A charge transfer device having a charge transfer channel in a semiconductor substrate. The charge transfer channel is formed by overlap of the possible electrostatic effect of the gates with the conduction layer. A clock generator has a clock frequency of more than 100 MHz which applies changes in potential at the clock frequency to the gates, for transporting charge carriers at the clock frequency from adjacent regions of the overlap between adjacent gates and the conduction layer. The charge transfer channel has an influx region which, in the flow direction, is arranged at a lateral outer boundary of the charge transfer channel and which at least partly extends over the regions of exactly two adjacent gates of the charge transfer channel in order to supply charge carriers to the charge transfer channel from a region outside the charge transfer channel that adjoins the influx region from a second charge transfer channel.
