  • Publication number: 20190070788
    Abstract: A device for calibrating an irradiation system of an apparatus for producing a three-dimensional work piece includes a control unit to control the irradiation system so as to irradiate a radiation beam onto an irradiation plane according to a calibration pattern. The device also includes a sensor arrangement arranged in the irradiation plane to output signals to the control unit in response to being irradiated with the radiation beam according to the calibration pattern. The control unit generates a digital image of an actual irradiation pattern produced by the radiation beam incident on the sensor arrangement based on the signals output by the sensor arrangement, compares the digital image of the actual irradiation pattern with a digital image of a reference pattern so as to determine a deviation between the actual irradiation pattern and the reference pattern, and calibrates the irradiation system based on the determined deviation between the actual irradiation pattern and the reference pattern.
