Abstract: The invention relates to an optoelectronic sensor for distance measurement that comprises a light source that is configured to convert a transmission signal into transmission light and to transmit the transmission light into an environment. The optoelectronic sensor further comprises a light receiver that receives transmission light reflected by objects in the environment as reception light, wherein the light receiver has an optical routing layer, wherein the light receiver has an image sensor comprising a plurality of sensor elements, wherein the sensor elements are configured to convert reception light into reception signals, wherein at least two sensor elements are part of a sensor element group, wherein the routing layer is configured to supply the reception light successively and/or alternately to the sensor elements of the sensor element group. The invention further relates to a method for a corresponding optoelectronic sensor and to a method for manufacturing a corresponding optoelectronic sensor.

Abstract: An optoelectronic sensor for detecting and determining the distance of an object in a monitored area is specified with a light emitter having a light source for emitting light pulses, a light receiver for generating a received signal from a light pulse remitted by the object and with a control and evaluation unit, which is designed to control the light emitter and to determine a time-of-flight of the light and, from this, a distance of the object to the sensor. The control and evaluation unit has a time measurement unit which is set up to receive the received signal and a trigger signal and to determine the time-of-flight of the light from a time interval between the trigger signal and the received signal. The sensor further has a trigger circuit that is set up to tap a voltage applied to the light source of the light emitter and to output the trigger signal when an amount of the tapped voltage exceeds a predetermined threshold value.

Abstract: An optoelectronic sensor (10), in particular a light grid, for monitoring a monitored zone (22) is provided, wherein the sensor has at least one light transmitter (14) for transmitting a monitoring beam (20), at least one light receiver (18) for receiving the monitoring beam (20) and for generating a corresponding received signal, and an evaluation unit (26) to recognize from the received signal whether the monitoring beam (20) is interrupted and to output an interruption signal on a recognition of an unauthorized interruption of the monitoring beam (20). The light receiver (18) is configured in this respect such that the received signal is dependent on the geometry of the light spot (30) generated at the light receiver (18) by the monitoring beam (20) and the evaluation unit (26) is configured to recognize from the received signal whether the non-interrupted monitored beam (20) is manipulated.
