Abstract: An optoelectronic sensor includes a plurality of light sources for generating transmission light, including at least a first and a second light source. The optoelectronic sensor includes transmission optics for projecting transmission light into the field of view and at least one detector for detecting transmission light reflected by the object. A photonic network has a plurality of irradiation points to each of which transmission light, in particular in each case of exactly one light source, can be supplied. The transmission light exits into the transmission optics and ultimately exits into the field of view. A plurality of irradiation points that are arranged directly next to one another or that are directly adjacent are in this respect configured to irradiate transmission light into partial fields of view, in particular different partial fields of view and/or a plurality of partial fields of view arranged next to one another or are adjacent.

Abstract: An optoelectronic sensor is provided that has an image sensor for the detection of image data in its field of view and an aiming device having a light source that is arranged laterally offset from the image sensor and that is configured to generate alignment light and thus a light pattern in the field of view to make the position and/or extent of the field of view in space visible. In this respect, the aiming device has at least one optical metaelement having a metasurface and/or a metamaterial that is arranged and configured such that the optical axes of the image sensor and the aiming device are coaxially superposed.

Abstract: A beam splitter arrangement for an optoelectronic sensor, an optoelectronic sensor having such a beam splitter arrangement, and a method of beam splitting in an optoelectronic sensor are provided, wherein the beam splitter arrangement has at least one input for coupling first transmitted light beams having first transmitted light pulses into the beam splitter arrangement. At least one beam splitter splits the first transmitted light beams into a plurality of second transmitted light beams having second transmitted light pulses. The beam splitter arrangement further has a plurality of outputs for decoupling the second transmitted light beams from the beam splitter arrangement, with the number of outputs being greater than the number of inputs. Optical compression paths that compress the second transmitted light pulses such that a second pulse length of the second transmitted light pulses is shorter than a first pulse length of the first transmitted light pulses are arranged downstream of at least one beam splitter.
