CAMERA AND METHOD FOR THE DETECTION OF A MOVED FLOW OF OBJECTS

摘要

A camera is provided for the detection of a flow of objects moved relative to the camera, comprising an image sensor for the taking of images of the objects and a receiving optics that is arranged in front of the image sensor and that has a depth of field range. In this respect, a mirror unit having at least two mirror elements is arranged in front of the receiving optics, the mirror elements having a different spacing amongst one another with respect to the receiving optics and/or having a different tilt angle and in this way imaging sections of the object flow a plurality of times with light paths of different length and in this way with different depth of field ranges at the image sensor.
