  • Patent number: 9677914
    Abstract: An optoelectronic sensor for recognizing object edges of objects comprises at least three light transmitters which are arranged such that at least two different spacings result between two respective light transmitters. For recognizing an object edge, an evaluation unit is configured to carry out a common evaluation of an image taken by a light receiver of a light spot generated by the transmitted light beams of a first light transmitter and of an image taken by a light receiver of a light spot generated by the transmitted light beams of another light transmitter. The pair of light transmitters to be used for the common evaluation can be selected in dependence on a selection criterion from at least two differently spaced apart pairs of light transmitters.

  • Patent number: 8482720
    Abstract: The subject matter disclosed relates to a method for the detection of objects, wherein one transmitted light bundle is transmitted into a detection region, transmitted light reflected back from an object, when present, is detected by a receiver unit having reception elements arranged in an M×N matrix, wherein M>1 and N>1, and the distance of the object is determined by triangulation from the position of the light patch produced by the reflected light at the receiver unit. In addition to the position of the reflected light, the two-dimensional energy distribution of the received light patch within the light incident on the receiver unit is evaluated to determine further information on the object in addition to the distance of the object determined by triangulation, with a light patch quality value being determined which includes information on the homogeneity of the light reflected or remitted at the object.

  • Patent number: 8248619
    Abstract: 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.

  • Patent number: 7391007
    Abstract: 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.
