More Information
Summary:The device has optical image acquisition units (21, 22) arranged for a continuous image data acquisition produced by line by line scanning by a sensor line and simultaneous relative movement between the sensor line and a scene. A mobile calibration plate (31) is provided for repeatedly providing a defined radiation intensity, which partially shades an image beam path of one of the image acquisition units, while the other image acquisition unit is free for the unhindered scanning of an over-coating scene. The calibration plate is inserted into a radiation path of the image acquisition units.
