ABSTRACT:
A method includes receiving a sheet of material at a sensor assembly. The sensor assembly includes a sensor configured to measure a property of the sheet. The method also includes stabilizing the sheet with respect to the sensor using a guide roller. Stabilizing the sheet includes using the guide roller to remove at least a portion of a first boundary layer of air moving towards the guide roller and to reform at least a portion of a second boundary layer of air moving away from the guide roller. For example, the guide roller could include a plurality of grooves or openings in a surface of the guide roller, or the guide roller could include a plurality of rings spaced apart from one another. Air could move from one side of the guide roller to another side of the guide roller through the grooves, through the openings, or between the rings.
