Abstract:
1. A process for the optical detection of objects moved at a conveying speed, the method comprising: illuminating an object with one of: taking images of the object during each light pulse with a monochromatic optical area sensor comprising a plurality of sensor lines, wherein each image is taken at a different time; reading out and temporarily storing lines of each image, wherein the read-out lines have a line pitch relative to each other, wherein by the line pitch or a multiple of the line pitch a projection of the object onto the area sensor moves along between consecutive light pulses, the line pitch or a multiple of the line pitch, respectively, being proportional to a distance for which the object moves along at a conveying speed between consecutive light pulses; sequentially combining lines from different images taken under illumination by the light pulses to form combination lines, with the lines combined with each other having the line pitch or a multiple of the line pitch, respectively, relative to each other; and assembling the combination lines into a combinatory overall picture.
