Abstract
An optoelectronic sensor has a light source ( ) for the transmission of a scanning beam ( ), a light deflection unit ( ), which is formed for the periodic deflection of the scanning beam ( ) within an angular transmitting range ( ), a receiving device for detection light reflected from an object to be sensed and/or back-scattered light, and a deflector ( ) which has a light entry surface ( ) arranged at least regionally within the angular transmission range ( ). The light deflector is formed for the deflection of light incident through the light entry surface ( ) onto a photo-detector ( ). The photo-detector ( ) can be coupled to a synchronization circuit to produce a synchronization pulse for the determination of the start of a sensing period.
