Device for the detection of objects with an opto-electronic recording unit, as well as opto-electronic recording unit

摘要

Device for the detection of objects (5) with an opto-electronic recording unit (1), comprising a to the or the objects or on a the or the objects (5) a supporting element (2) and directed through an objective (3) to be focused a photosensitive, to an evaluation unit connected to the sensor array (4), characterized in that, in the beam path of the objective lens (3) an element (6, 12, 13, 14) with a transparent and light is not effective passing areas specified structuring is switched on, so that a not focused in the region of the objective lens (3) with a light source located in the structuring of the element (6, 12, 13, 14) corresponding contouring on the photosensitive surface of the sensor array (4) is imaged, whereas a mapping of in the focus of the objective (3) of the objects (5) on the photosensitive surface of the sensor array (4) is not effective with respect to their contour shown by the element (6, 12, 13, 14) is influenced.
