<p><strong>Abstract.</strong> In food industry, most finished products are scanned by X-ray for contaminations. These X-ray machines continuously scan the product passing through. To minimize the required X-ray power, a Time, Delay and Integration (TDI) CCD sensor is used to capture the image. While the product moves across the sensor area, the angle of the X-rays changes during the pass. This can be compensated for by adjusting the sensor shift speed to focus on a single plane of the product.doi:10.5194/ars-9-135-2011 fatcat:kqsta75yvzafvlqyityfyjcdiu
