Abstract
An optoelectronic sensor in accordance with the principle of triangulation for detecting an object in a monitored zone is provided that has a light transmitter and a transmission optics associated with the light transmitter in a transmission path for transmitting a light beam, and a spatially resolving light receiver and a reception optics associated with the light receiver in a reception path for receiving the light beam remitted by the object, as well as a control and evaluation unit that is configured to evaluate a received signal of the light receiver. The sensor furthermore has an optical metaelement having a metasurface and/or a metamaterial in the reception path.
