Abstract
An optoelectronic sensor (10) has a light receiver (16) for converting received light from a detection area (12) into an electrical signal. The sensor (10) comprises an evaluation unit (18) for obtaining information about objects in the detection area (12) from the electrical signal and aiming means (22) having at least one light source (24) and a pattern generating element (28) to make the detection area (12) visible with a light pattern (36). The pattern generating element (28) comprises a plurality of cylindrical lenses (30, 32, 34) so that the generated light pattern (36) comprises a plurality of lines (38) showing the position of the detection area (12).
Claims12
An optoelectronic sensor (10) having a light receiver (16) for converting received light from a detection area (12) into an electrical signal, the sensor (10) comprising an evaluation unit (18) for obtaining information about objects in the detection area (12) from the electrical signal and aiming means (22) having at least one light source (24) and a pattern generating element (28) to make the detection area (12) visible with a light pattern (36),
- characterized in that the pattern generating element (28) comprises a plurality of cylindrical lenses (30, 32, 34) so that the generated light pattern (36) comprises a plurality of lines (38) showing the position of the detection area (12).
A method for detecting object information from a detection area (12) and for visualizing the detection area (12), wherein a light receiver (16) converts received light from the detection area (12) into an electrical signal which is evaluated to obtain the object information, and wherein a light pattern (36) is generated in the detection area (12) to make the detection area (12) visible,
- characterized in that the light pattern (36) is generated as a plurality of lines (38) by means of a plurality of cylindrical lenses (30, 32, 34), the position of the detection area (12) being shown by the lines (38).
