Abstract
An optoelectronic sensor arrangement (), with a plurality of optical transmitters () positioned side by side in an optical transmitter strip (), such that each optical transmitter () transmits the light of a transmitted cone (α) into a surveillance area (), and with a plurality of optical receivers () positioned side by side in an optical receiver strip (), which optical receivers () receive the light of a received cone (β) from the surveillance area (), where each receiver ()comprises a spatially-resolving element (), such that each optical transmitter () and optical receiver () form an optical receiver/transmitter pair, and a control unit contains means for determining the optical incident point (L, L', L, L) on one of the optical receivers () of the transmitted cone (α) of each optical transmitter () and/or of a foreign light source (G).
