    摘要: A light barrier detects an object which interrupts a beam of light of the light barrier. A light transmitter transmits a light beam in the direction of a reflector and a light receiver receives a reflected portion of the light beam. The improved light barrier has a reflector which is made as a cylindrical reflector column having a plurality of retroreflecting elements aligned toward the outer surface. The diameter of the reflector column is considerably smaller than the extent of the light beam perpendicular to the cylinder axis so that an optically effective detection beam of light is formed between the sensor and the reflector column whose cross-section at the sensor is determined by the light transmitter and, in direct proximity to the reflector column. The cross-section is determined by the areal overlap of the light beam with the reflector column.

    摘要: A method for the detection of an object includes transmitting light in the direction of a reflector by a transmitter. The transmitted light is reflected by the reflector and is imaged as a reflector image and is detected by the receiver. The reflector image is evaluated and an object detection signal is generated if an at least partial interruption of the transmitted light is recognized. A light object incident onto the receiver outside the detection region is detected by the receiver, is examined for predetermined object properties and is classified as a reflector image or as an interfering light object based on the object properties. In the case of a classification as an interfering light object, a movement of the interfering light object on the receiver is determined and the generation of the object detection signal is executed based on the determined movement of the interfering light object.
